HELP! Troubleshooting Gnocchi...
- Juniper Jan 26, 2012 02:55 PM
So I tried to make gnocchi tonight...
I had about 1 kg of potatoes cooked and mashed. Added a 1/2 cup of flour and one egg. Mixed it all together. It failed to really resemble a doughy mass, and it was instead incredibly sticky. I thought this was an indication that the mixture needed more flour. So I added a bit less than 1/4 cup of flour and mixed it all in. Still too sticky. Added another dusting of flour and incorporated it. The dough became even stickier than it was before!!
Any idea what went wrong??
how did you cook the potatoes? baked is best, as it doesn't add any extra moisture.
what kind of potatoes did you use? i prefer russet for having the lowest moisture content.
did you rice/mash the potatoes when they were finished cooking and still hot? if you wait til they cool, the flesh starts to take in moisture.
what kind of flour? i like to use 00 flour if i have it or i do a combo 2:1 cake:all-purpose. also 1/2 cup is awfully light.
Egg - sometimes i eliminate it, as it isn't in the most traditional of recipes. egg white only will make it tougher and chewier. egg yolk will make it richer but stickier dough.
how much mixing did you do? did you overwork the gluten?
what i use...
~2 lbs russet potatoes - baked (rice immediately after out of oven)
1 egg + 1 yolk (sometimes just the egg, sometimes none)
1 cup (00 or cake/ap blend) flour to start - may need a little more
I'm not really seeing how more flour could make it stickier. Unless there's something you're not telling us, I'm not going to be able to give you any help on that front.
A little sticky is alright, btw. As long as you can still work it.
Emme is giving you good advice. A big principle of making good gnocchi is to have as little extra water in the dough/potatoes as possible. On top of her suggestions, I suggest using a ricer while the potatoes are still quite hot and then spreading the riced potatoes out on a flat surface to let some of the steam escape for a bit before adding the flour. It should still be pretty warm when the flour goes in (or at least that's how I do it). I also get better results without an egg than with, though I know some people use egg to good results. Many people say that using older potatoes helps as well, if you can reliably determine the age of your potatoes (I've never really managed or bothered to).
When you're rolling them out, a key to fluffy gnocchi is to keep them loose - just barely holding together well enough to survive cooking.
I only succeeded with russet/baking/starchy potatoes. I have had sticky dough and leaden gnocchi using both fingerlings and Yukon golds (which are both better roasted or boiled for potato salad in my opinion).
I'm having some problems myself, and I'm hoping I can get some guidance. I've tried to make gnocchi unsuccessfully several times now. They always turn out some combination of mushy, slimy, and/or grainy.
Here's a photo of my most recent attempt. When I was rolling out the dough, it did something..odd. It's like a seam opened up somehow in the dough. This seam is circled in red - you can see the patches where the dough just isn't a cohesive mass.
I'd love to get some feedback, because I love good gnocchi, but I just can't seem to replicate it at home!
can you post your recipe? it looks like your dough is too dry, at least on the exterior. if you've got flour coating it, those pieces aren't going to seal together. my guess is your issue includes too much flour and overworking the dough... please let us know your recipe and methodology to get a better answer.
I used this recipe from Simply Recipes:
*2 lbs whole baking potatoes
*2 beaten egg yolks
*1 1/2 cups flour
*Pinch of salt
I baked the potatoes and scooped the flesh out as soon as I pulled them from the oven. I don't have a potato ricer, so I gently mashed the potatoes with a fork and then walked away for an hour to let them cool. I poured the egg yolks over, and then began to add the flour.
However, I have read over and over that you should only add enough flour so that the dough has "just come together." I put in more like 1 cup of flour, not the 1.5 cups the recipe calls for because I could tell that adding any more would cause the dough to become overly dry.
What I don't understand is: how could my dough possibly be too dry when I added only 66% of the flour specified by the recipe?
yes, my comment was directed at the Original Poster who is having a gummy problem.
It sounds like you are having a different problem. First let me say, making gnocchi is not ever an exact science are actually very hard to get right without some hands on training from someone who has done it before (in my opinion). This is mainly because potatoes are so inconsistent in terms of moisture content, texture, etc. So knowing what it is supposed to feel like is important.
I don't use egg when I make gnocchi (that is how I was taught) and my understanding is that it is used in many recipes because it helps the gnocchi hold together in the end which can help "fix" other minor variations when making them.
I also don't let my potatoes cool quite as long as it sounds you do. I bake my potatoes, scoop out the inside, mash (I use a ricer but wasn't taught that way originally), let them cool just until I stop seeing steam rising from them. You can of course let them cool longer (I know many people that do but I wasn't taught that way).
I then sprinkle flower over the top of the potatoes that are essentially spread out about a 1/2 thick - ish - (I don't measure so I don't know how much to tell you honestly or I'd be happy to) - but I sprinkle flower over the top until it looks like a light snow over them (not enough for a real layer of flower but enough so you can tell it is there). Using a bench scraper I then almost "chop" the flower into the potato rather than mixing, then "fold" up all the potato like folding a letter into one mass. Then chop it apart to spread it back out into a similar 1/2 in thick sheet. Repeat sprinkling the flower, chopping, folding. I do this for about 3 additions of flour total. At that point it holds its shape when folded into the final block shape. It is still a little "sticky" so I lightly flour it when I roll it out. Cut, boil, and then I like a crispy outside so saute in butter.
That is my method as best as I can describe it. Most recipes I've ever read call for WAY too much flour (in my opinion) so I wouldn't be worried about using less than the recipe calls for. Your picture reminds of times when I'm hand rolling breadsticks. It is very easy in that instance to have too dry of dough and then when you flour it and try to roll it out you can easily end up with those types of "cracks" or "pockets" that wont stick together and never come together when you are "making a snake" (as the kids say). So from your picture I would have to agree you may have a combination of problems - one being too much flour (given the moisture content of your potatoes) the other could be overworking our dough when mixing.
Marco Canora's method is the most similar to how I learned to do mine (or at least who has online videos). I did a quick search and found this page with a video at the bottom of him describing how he makes his gnocchi. Maybe it will help. Gnocchi are too good to give up on!
re: fame da lupo
I've had pretty good luck with gnocci.
I boil the potatoes whole and avoid sticking them with a fork too much, and peel them and run them through a ricer immediately, while still piping hot. Then I add the flour (low gluten) but no egg, and quickly mix until it's still very slightly tacky, but easy to handle.
I agree, no need for egg. I used one russet and 1/2 cup of flour and they turn out like delicate little pillows. I am not allowed to link to my blog but if you search "melbo's toast gnocchi" you can see pictures of what the dough looked like after I mix it and after they are rolled out.
Okay, so basically I think I blew it. I got sidetracked and let the potatoes sit in water (did not read this before) for a while, then added a TON of flour (again, before I read this) and the dough is still a sticky lump. I have yet to get said blob of sticky dough out of the bowl. Is there any way I can repair/save these?
