Unrefrigerated Tomatoes -- I Still Don't Get It

Okay, I heard it here on CH that refrigerating tomatoes was not a great idea, so recently I tried leaving my very ripe, from the shuk, tomatoes out at room temperature. Within a couple of days, at temperatures in the 30s C (90s F), all were unpleasantly soft and some were moldy.
Now I'm back to storing them in the fridge. And they taste fine. In fact, I'm just finishing a tomato/cucumber/avocado/sweet pepper/harif (hot) pepper/red onion/fresh basil/lemon juice salad that tastes more than fine.
So I'd like to hear more specific instructions than just "fridge is bad, counter is good."

  1. Well, one should eat tomatoes when they are ready to eat; especially when they are VERY ripe; leaving them outside in a hot environment will accelerate the ripening (sp?) and they will start to rot.

    Putting tomatoes in the fridge will slow down the aging and decaying of ripe tomatoes.

    Leaving tomatoes out of the fridge, at least those that are not yet ripe enough will help them ripen and IMO give them better taste; and I hate cold tomatoes (and cold raw veggies in general)

    1. The cold temperatures of the refrigerator will ruin the texture of a tomatoe and make it mealy.

      If your tomatoes were very ripe then you should have just eaten them.

        I agree with jpc - if your tomatoes are very ripe, eat them.
        Make a fresh pasta sauce or bruschetta.

        I'm the the mid-Atlantic states, and the only tomatoes I buy
        in the winter are grape or cherry to throw into a salad.

        In tomato season, I don't get to the farmers' market every
        day so I try to select tomatoes at varying stages of ripeness
        to last over a few days and definitely store them on the
        counter. I find a distinct difference in taste and texture with
        refrigerated tomatoes but if you don't have AC that might
        be your only option.

          "try to select tomatoes at varying stages of ripeness
          to last over a few days and definitely store them on the
          Great advice. And if you find some getting too ripe, make sauce and freeze it - there's nothing like the taste of summer tomato sauce in February.

      2. LOL! You're joking, right?

        At that ripeness and at those temperatures, you got exactly what you should have expected.

        "Very ripe tomatoes" aren't to be stored.

        "Very ripe" tomatoes, being very tasty, lose just as much flavor from the cold storage as do any tomato of any ripeness. But since the "very ripe" tomato is so much more flavorful, the cold storage still leaves plenty of flavor behind.

        If you started with a less ripe tomato the cold would leave them flavorless. This may only be noticeable to some people who are not used to cold stored tomatoes. If some people are used to cold tomatoes, then room temperature tomatoes aren't pleasant.

        Having grown tomatoes in my vegetable garden for many, many years I have been able to pick vine ripened tomatoes to enjoy the same day or next without much problem. If tomato crop is overabundant, then sharing with friends and family or sauce or jarring may be in order. If I see that many will ripen at once then I pick them the *day before* and store at room temperature for a few days.

        BTW, where are you located? Curious for two reasons. First, that much *stuff* on a tomato salad is NEVER going to make a difference if you have "very ripe" tomatoes or unripe green tomatoes. Lemon juice or vinegar on tomatoes is blasphemy. I see everyone do it and I cringe. Cannot and will not ever like it. Ever. Horrible treatment of tomatoes. Horrible. Second, at this time of year, where are you getting your "very ripe" tomatoes?

        Also, *very ripe* tomatoes are an American thing. Travels through Italy and Greece show that *salad tomatoes* are under ripe tomatoes meant to hold up in a salad. *Very ripe* tomatoes fall apart and are meant to be eaten out of hand.

        1. re: Gastronomos

          Lemon juice and tomato is a very common marriage in the Middle East. Salads of tomato, cucumber, olive oil, lemon and salt are quite common, along with a variety of other preparations.

          I can't speak specifically to almond tree's tomatoes - but as someone who lives in Jerusalem, tomatoes are largely used by home cooks for salads/raw preparations. So ripeness is more frequently judged on their ability to work within a salad/raw. Unfortunately for me, most tomatoes I buy now end up in the fridge because the size of my kitchen does not have so much counter space.

          1. re: cresyd

            Ok. Being from Cyprus myself, I get the lemon juice and tomato thing. I also repeat that under ripe tomatoes are more traditional for these preparations that you mention. Underripe.

          2. re: Gastronomos

            Not joking, just trying to learn something new. That's exactly why I posted -- to find out exactly what the idea of not storing tomatoes in the fridge is all about.
            I can't go shopping every day, so I usually buy enough tomatoes for a week at a time.
            I put "that much *stuff*" on my salad quite simply because I like it, ***especially*** the lemon juice :). (Cresyd is right, it's a regional thing.) The tomatoes weren't the star of the show, just a very nice component.
            Where I'm getting my very ripe tomatoes -- I live in Jerusalem, so tomato season is in full swing already and will be until October or November.

            1. re: almond tree

              Ok. If you like refrigerated tomatoes, go for it. If you can't tell he difference, go for it. Being from Cyprus myself I get the lemon juice thing. It's more traditional to use underripe tomatoes. Underripe.

              1. re: Gastronomos

                Huh? I didn't say I prefer refrigerated tomatoes, just that I can't shop for them every day.

                1. re: almond tree

                  "Now I'm back to storing them in the fridge. And they taste fine. In fact, I'm just finishing a tomato/cucumber/avocado/sweet pepper/harif (hot) pepper/red onion/fresh basil/lemon juice salad that tastes more than fine."

                  I think what Gastronomos was saying is that you seem to not have any flavor or texture issues with a refrigerated tomato so why not just keep doing as you are doing? I think for many folks, myself included, refrigerating dulls the flavors and changes the texture - making the tomato mealy and even gritty. Kind of like a bad apple. But if that doesn't happen for you then that's great! Maybe Israeli tomatoes are a hybrid or variety that stands up to refrigeration. Whatever the reason, enjoy your maters and your delicious salads (that salad sounds lovely). :)

                  1. re: lynnlato

                    I haven't noticed a change in texture, although the local style is to chop all salad ingredients quite fine and to let them sit together and "marry" for a while, so differences in texture would be less noticeable than if I were eating them in thick slices.
                    In terms of flavor, the summer tomatoes in Israel (which are already on the stalls in the shuk) are intensely flavorful, so some slight loss of flavor would probably be insignificant.
                    I guess I can do a comparative taste test to find out for sure :).

                  2. re: almond tree

                    Just enjoy them room temp or cold. There is a difference but its not night and day. No sin

                2. re: almond tree

                  Most of the tomatoes that most of us buy are picked green and refrigerated before we get them. These tomatoes have had their cell walls and enzymes damaged, and can never taste good. Ripe tomatoes are another matter. Harold McGee advises to let ripe tomatoes that have been refrigerated sit on the counter for a day or two before eating them. This is supposed to help them recover.

                  1. re: bcc

                    Thank you for a clear explanation.

                    1. re: almond tree

                      Do you think that happens to tomatoes in Israel? Given the abundance of tomato in the local diet, I have always assumed that a good chunk of the tomatoes we get go through some kind of large scale agricultural meddling - but I don't really know much about the life of the average tomato sold in Israel.

                      1. re: cresyd

                        I don't think tomatoes are usually picked green in Israel. They are transported much shorter distances than is often the case in North America. Also the turnover at Machane Yehuda is very high and Israelis are pretty demanding of good quality produce.
                        So my conclusion is that we don't need to be so concerned with leaving tomatoes on the counter here, although I would like to try taking out whatever amount I plan to use that day, to let it come to room temp.

                        1. re: almond tree

                          I agree that you should do whatever works for you, but please don't get the idea that high quality or vine ripe produce survives refrigeration better somehow.

                          There's no way in the world I'd put the tomatoes I grow in the fridge. It destroys both flavor and texture. Sometimes if I by crappy grocery store tomatoes and want them to last longer, then I will refrigerate...because they suck already.

                          btw, peaches are similarly destroyed by refrigeration.

                    2. re: almond tree

                      Thanks for the "season" update! Was reading everyone else talking about "winter" tomatoes, and thinking, "okay, when's winter in the Middle east?"
                      (If i remember right, that means dry season is tomato season, and wet season is not tomato season?)

                      1. re: Chowrin

                        Winter in Israel is basically the same time as in North America -- it's just shorter and rainy rather than snowy (although we do have a snowfall every couple of years). You are right, that is not tomato season -- tomatoes are still available in the stores, but they are expensive, poor textured and tasteless.
                        The long sunny dry season starts some time in March or April, so by now this year's tomato crop is in full swing.

                    3. re: Gastronomos

                      Give Marcella Hazan's Garlic Scented Tomato Salad a try. It may just change your opinion about vinegar and ripe tomatoes.


                      1. re: EM23

                        You had me at vinegar and ripe tomatoes. I love both! I enjoy red wine vinegar much more than balsamic vinegar so this will be a wonderful spin on bruschetta which I often just throw on top of chicken.

                        1. re: fldhkybnva

                          Such a simple recipe, but so delicious. Make sure to follow the marinating garlic and salt in vinegar step. It infuses the 'maters with great flavor. Is it July yet???

                        2. re: EM23

                          Thank you. I will note that she states, "ripe, firm, round or plum tomatoes"
                          That is not the same as very ripe tomatoes. Very ripe are usually not firm and she also goes on to say to skin the raw tomatoes. I have not had much luck skinning very ripe tomatoes. Even on occasions where I get garden tomatoes that are of the thick skin variety.
                          How ripe a tomato should be for a salad is preference.
                          Marcella Hazan also writes to a certain audience...

                          Being of Greek heritage I can say that a true Greek Salad has no lettuce in it at all. Tomatoes, cucumber, sliced raw onion, green peppers, copious amounts of olive oil and salt. A variety of personal favorites like capers and olives etc. But NEVER vinegar. It's a regional thing. On the island of Cyprus underripe tomatoes (they call them "ripe", as in "ready to eat") are diced with cucumber etc. and lemon juice is added. The acid missing from the ripe tomato is made up with lemon juice. The lemon juice also acts as an antiseptic.

                            I've traveled all over Greece for months at a time and had Horiatiki every day and every one had red wine vinegar on it.

                              Was the salad served dry? Or was the salad served dressed?

                              1. re: Gastronomos

                                Interesting. I used to make horiatiki with olive oil and lemon juice (in my younger days when I despised vinegar -- I hadn't had any good one), but it never tasted right.

                                A Greek friend of mine told me that's b/c they use red wine vinegar, not lemon. He's a mainland Greek. Maybe that's what you say about regional variations. I know a few Cretes I could ask.

                                I love a well-made horiatiki, but primo tomatoes and good feta are essential for it to taste right. And good olive oil. And 'rigani.

                                Damn, do I have a craving now....

                                  Yes, very ripe tomatoes are hard to skin. I make sauce with them and the skins usually peel off in the pot while it simmers and are easy to pick out.
                                  Being of Irish heritage, tomatoes, garlic and red wine vinegar were not on our table growing up. I am grateful every time I cook for the lucky day, at the age of 18, when I found a copy of Hazan's Classic Italian at a library book sale. :)

Your preferences don't necessarily dictate mandate, mine either. You like them au naturel, fine, but please try to refrain from such judging!

                                    In Greece, oil AND vinegar/lemon juice are added to all salads- Horiatiki (village salad), Lettuce, shredded cabbage/carrot, boiled greens, egg/tuna salads etc etc Salads arrive already dressed at Tavernas and Restaurants usually with Oil AND Vinegar bottles on the table for those who want extra.As for the ripeness of the tomatoes, fully red yet firm tomatoes are preferred, but occasionally tomatoes that aren't fully ripe (red) are used.

                                          My 3am attempt at a witty way to point out that the posts ignore a pillar of Greek cooking- the pillar of salt. Greek cooking often has far too much salt but it does go with heavy cigarette use. But the Greeks are OK in comparison with the Russians. So much salt! Revolutionary cooking- the dish revolts and my body rebels.

                                          The posts talking about Greeks and Italians using unripe tomatoes in salads do not recognize differences in variety, terroir, season and handling. Variations in tomatoes and use are almost as great as variations in grapes and wine.

                                          almond tree. There are all kinds of tomatoes in Israel. One kind is very fleshy and dense. It just sits on the shelf and nothing happens. Eventually it starts to wither but it is still OK to eat. There are compromises in every breeding programme. Consider the British Royal family.

                                          You were so lucky to get tomatoes perfect to eat the day you bought them! Or, when life gives you a ripe tomato- to make the next day matbucha (concasse, you can raise the price) or shakshuka. No waiting!) How much were they in comparison to other tomatoes at the market? Was it very humid at the time?
                                          Learn to love your tomatoes!

                                          I am an expert at garbage in the market but I certainly did need a crash course when I got to Israel.

                                          Incidentally, the modern commercial cherry tomato is the product of Israeli research and development. Small tomatoes for a small country.

                                            Shalom (or should I say "salve"), Vinnie,
                                            The tomatoes I bought were just regular Machane Yehuda ones -- nice but not out of the ordinary compared with their fellows.
                                            Since I only get to the shuk once a week at most, I bought a lot and decided to try leaving some out at room temp. I then scientifically proceeded to forget about them (during a spring heat wave -- hot, not humid), and when I found them a few days later, they were not happy campers.
                                            I think the whole discussion in this thread arose because folks living in the US assumed that early May tomatoes were dismal supermarket/hothouse produce, which would be in need of ripening.
                                            This was not the case with mine.

                                  3. If they are not as ripe as you would like them to be leave them on the counter. If they are fully ripe, either eat them immediately or put in the refrigerator.

                                    Just say no to dogma.

                                      This has worked for me. The grape tomatoes aren't always at the ripest and so they seem to last for up to 2 weeks on the counter with no noticeable change in quality. If I buy vine-ripened whole tomatoes or fresh ready-to-go ripe tomatoes we eat them immediately. I never refrigerated tomatoes as I don't like the texture.

                                    2. No produce ever tastes as good once it's been refrigerated as it does before.

                                        Apples and pears need to be held in cold storage to ripen. No pear varieties and very few apple varieties can ripen on the tree. If you try to let them do so, they rot.

                                            Oh, also I refrigerate leftover sliced tomato. It would never last another day otherwise. And when I make a tomato and onion salad I store it in the fridge but will always let it come to room temp before eating. Cold tomatoes are ick.

                                                Some the best apples I have ever had have been right off the tree. I dream of local macouns…

                                                  I grew up with both apple and pear trees, and they always ripened beautifully on the trees with no rotting.

                                                  Grapefruit is actually much better at room temperature, as are apples, peaches, pears, and other fruits that I can't think of right now.

                                                    There are a few varieties that ripen well on the tree. Most don't.

                                                    All the rest is all about personal taste. I cannot imagine anything more vile than warm citrus. But hey, if you like it....

                                                        I have lovely memories of pink grapefruit picked off the tree on a hot day and eaten right then and there.

                                                      I eat apples off the tree every autumn and they taste delicious. Maybe they aren't ripe (how do you define that in an apple, anyway), but they taste better just picked (crisp, juicy, slightly sour) than they ever will sitting on a shelf or in the fridge a day or two later. Ditto for Asian pears. If I don't pick 'em, I don't want 'em.

                                                          there was a pear tree in a windrow in one of the fields in the area where I grew up.

                                                          In the fall, we'd anxiously await the weekend when we would climb the tree, sit in the branches (4 of us!) and munch pears right off the tree.

                                                              it's true that apples and pear TREES have to have a certain period of cold weather in order to set blossoms and fruit -- perhaps that's gotten melded into the theory somewhere.

                                                              But no -- the fruit will ripen right there on the tree...the human race has been eating apples and pears since several centuries before there was refrigeration.

                                                        3. Very ripe tomatoes need to be eaten.

                                                          It's proven fact that refrigeration ruins the taste and texture of tomatoes.

                                                          But if you don't notice the difference between fresh garden tomatoes and winter supermarket tomatoes then by all means carry on.

                                                            I grow tomatoes by the bushel and sometimes refrigeration is the only viable alternative I have to letting them spoil. I have not noted the degradation of quality that others report. In fact, my experience mirrors that of the OP, "they taste fine."

                                                                Can you be clearer about that 'ruins the taste and texture'?

                                                              3. If it is necessary to buy more tomatoes than can be eaten before they go bad, by all means refrigerate them. Better to do that than buy and discard them several days later when they rot. Perhaps an optimal solution is to buy fewer tomatoes at one time. Tomatoes' taste and texture suffer under refrigeration, no doubt about it.

                                                                1. I was wondering much the same thing - but then I read somewhere that our supermarket tomatoes are put into cold storage until they are ready to be put out on sale - and the condensation I've observed on tomatoes recently put out on display would support this. So in this case, it probably matters little whether you refrigerate your tomatoes or not - the damage has been done, they have been refrigerated before they were even brought home.

                                                                  I did a side by side comparison with a freshly picked tomato I grew and a supermarket tomato and there was no contest, flavour and texture wise. You just can never be sure how the tomatoes you find in the supermarket have been stored.

Given the time, money and effort you spend to grow your own, I will never grow my own again.

                                                                    1. re: acgold7

                                                                      I like gardening, and tomatoes are so easy to grow - so it's a no-brainer for me. Plus if you get heirloom varieties and save the seeds, they're free after the initial outlay!

                                                                      I hate paying $3.00 for a tiny punnet of cherry tomatoes at the supermarket... or $6.00 for a kilo of romas, knowing how easy they are to grow.

                                                                      I guess it would be very different if I didn't care for gardening that much.

                                                                      1. re: acgold7

                                                                        1. re: acgold7

I admit that some of it is surely in my mind. I get a great deal of satisfaction from gardening and even things that I can tell are objectively not any better from my garden still seem better somehow.

                                                                          When people ask me about gardening I always tell them it is only worthwhile if you enjoy it.

Plus for a coupla dollars and the three minutes it takes to put an heirloom plant into the ground, you get, what, at least five or six beauties? Each of which tastes way better than anything available in a grocery store anywhere (but, then again, my homegrown are never refrigerated - in fact, sometimes they're not even washed).

                                                                            I spose sometimes you need to take a minute and a half to water 'em with the hose, but I just don't see how growin' tomatoes could be a lot of work.

The deer where I live (1st ring suburb) have totally decimated the heirlooms I've grown as soon as they flower; I mean, they mowed them down! Nothing deters these deer; they are fearless and resourceful. I now spend my money on tomatoes from the numerous local farmers' markets. Thankfully, deer don't seem to be interested in most herbs, so that's what I grow now.

You will not find a blemish at many chain supermarkets. In my area, Safeway, Giant, Harris Teeter can't sell tomatoes that are bruised. They will pay a premium for good looking tomatoes that stand up to long-distance trucking. They could be expensive, rock hard when bought, mealy when ripe, and flavorless. Does not matter.

                                                                              1. re: ursy_ten

                                                                              2. Also; when people say "don't refridgerate" they mean keep at around 70-80 degrees. If you have a root cellar, a place where there's wind and relative coolness/darkness, they may keep better.

Keeping a tomato at "room temperature" in that environment may mean a temperature difference of 10-20 degrees F higher than what McGee implies by "room temperature". That's why the OPs very ripe tomatoes are rotting at room temperature.

                                                                                      And, as a scientist, neither this nor the previous link is science. It's just someone else's opinion.

I tend to trust McGee not to just pull nonsense about enzymes and cell membranes out of his *** and publish it, but if you, as a scientist, can show that he's wrong, I think all of us would be interested in hearing about it.

                                                                                        I think most people (including Israelis) understand more or less what "room temperature" refers to, and that the should adjust accordingly if their actual room is significantly cooler or warmer than this. [On second thought, I have no idea if most people understand this, and of course I agree with your comment about stuff rotting faster in warmer environments. Harold McGee also says this…]

                                                                                  1. If the choice is between the refrig and the trash bin, I vote for the former.

What do you care what others say or think? We can all give you our specific instructions one what we have found in our experience but does it matter? If you are happy and they taste great then enjoy!

It's like the cold leeches the flavor and juicy texture out. I get a farm share and in August I am over run with tomatoes along with the ones I grow myself. I can get pretty creative but if they look like they might rot I invite friends over or I make sauce.

                                                                                      1. I read somewhere that when ripening tomatoes on the counter, they should be placed with the stem side down. This deters the ability of bacteria or fungi to enter via the vulnerable area surrounding the stem, so the fruit stays in good condition longer.

                                                                                        2. There is a good scientific reason not to refrigerate tomatoes -- it is not a matter of opinion or preference, but science. Some of the enzymes necessary for the development of the characteristic flavor of tomatoes as they ripen are destroyed by being chilled to less than 55 F. Once a tomato has been chilled to 55 or less it can never ripen properly and develop the flavors that we associate with a good tomato. If it has already ripened and is then chilled, well, that's another thing.

                                                                                          Poor handling (chilling) is doubtless one important reason that "supermarket" tomatoes are not as tasty as home-grown ones (though there are other well-known reasons of course).

                                                                                          I have often seen tomato cases (wholesale size) with directions printed on the side directing downstream handlers to not chill them.

                                                                                          2. Why would you store ripe tomatoes at 90+ degrees? Were you attempting to debunk an idea that you didn't want to agree with no matter what?

                                                                                            Cold does "turn off" some flavors in the tomato. I can taste it, therefore there is a difference (to me).

                                                                                            Our tomatoes simply sit on the counter or in a fruit bowl until we use them or throw them out. If we cut one and don't use it all, that piece goes in the fridge...and there is a definitive difference in taste unless we bring it back to room temp before eating.

                                                                                            If you're taste receptors can not differentiate between cold or room temperature tomatoes, I would wholeheartedly not worry about it.

In the seasons I grow tomatoes, or when I buy them from the farmers market, I leave them out in the kitchen and they last for like a week.

It is one of the major volatile compounds in ripe tomatoes. It is produced in small amounts by most plants and it acts as an attractant to many predatory insects. It is also a pheromone in many insect species.

                                                                                                    cis-3-Hexenal is an aldehyde. It is relatively unstable and isomerizes into the conjugated trans-2-hexenal. The related alcohol cis-3-hexen-1-ol is much more stable. It has a similar but weaker smell and is widely used in flavors and perfumes.

                                                                                                        Someone in an office in where ever calls someone in Arizona and a railcar load of tomatoes shows up. These are shipping tomatoes , not eating tomatoes.

                                                                                                      2. This cis-3-hexanol thing: in plants and fruits and such, besides the obvious basic things like sugars (sweet) acids (sour) and such, flavors are created by volatile organic compounds. In fruits, they're usually esters, and often times just one specific ester can be found creating the one "identifying" flavor. There's one ester that smell strongly of bananas, another that smells strongly of strawberries, etc. This is where artificial flavors come from, they're the chemically produced or isolated-from-other-things versions of these chemicals.
                                                                                                        However, usually, there's a whole slew of esters and aldehydes and ketones that produce the complex aromas/flavors of plant foods. Even when one ester has the "identifying" flavor, a lot of other flavor notes come from various other flavor aroms compounds. This is why artificial flavors lack the complexity of real flavors (though make no mistake, people overwhelmingly report the artificial flavors as better in tests. this is because with artificial flavors/extractives, the flavors are in liquid form throughout the food, easily volatilizing and producing the scent, as opposed to being trapped in plant cell walls. And on top of that, flavor companies do their best to include all those odd chemical notes to create a more complex flavor. It's a whole industry, with some very high-paid individuals with amazing noses, and good proprietary flavor mixes can cost a pretty penny for food factories who want to use them)

                                                                                                        For all of those flavor "notes", scientists have actually isolated individiual chemicals, each with their own note or scent. ALone, these chemicals give vague but familiar smells. This cis-3-Hexenal is reported to have a intense grassy-green odor of freshly cut green grass and leaves.

                                                                                                        Now, at the very least, refrigerating tomatoes will make this note less volatile. I dunno about it "turning off" like Alton Brown is saying, it's not an enzyme, so it doesn't do that sort of thing. But the wikipedi article says that it's an unstable molecule that can isomerize into another chemical, so maybe that's what's happening.

                                                                                                        Either way, does this one chemical scent-note not being there really make such a difference? I'd actually doubt it, but it doesn't hurt to keep it around. And let's not forget in general volatile compounds won't be as volatile in the fridge.

                                                                                                        Alls I know is the only tomatoes worth eating for me are the ones I grow or buy from the farmer's market and never refrigerate, and they last a while on the counter. Of course they won't last at 90f, but why on earth is your kitchen that hot? That's crazy. The only other tip I have is don't put them in direct sunlight. Do you have a cellar maybe? Maybe a little fridge you could set at 50f? That's always made me think, they need a produce fridge, nothing lasts in normal fridges because of all the dryness, and it's way colder than it needs to be for a lot of produce. Just a little fridge that stays at 50f and keeps it humid inside and also provides some ventilation and fresh air.

                                                                                                        Rest of the year, it's canned tomatoes or sauces, which are made in season from fresh, vine-ripened tomatoes and then canned, which is still better than the faux-red baseballs you get at the supermarket (picked green and "ripened" with ethylene)

                                                                                                        1. Even though refrigerating is "not a great idea", I firmly believe that storing food in ways which enables us to eat said food is better than allowing food to spoil. So, if your kitchen, like mine, stays "hot" (by North American standards) then to ahead and refrigerate food. Some items, such as tomatoes, will taste better if allowed to come to 15-20º before consuming. Basically, chilling is one method to slow down spoilage. Less spoilage = less waste.

                                                                                                            But if you refrigerate an unripe tomato, and possibly even a ripe one (I think the jury is still out on the latter) you've wasted it anyway, for the scientific reasons discussed above. Unless of course you don't care much how it tastes.

                                                                                                            you don't have to get it.

Add in a heat wave room temperature of 30-odd degrees plus no air conditioning.
