I need blue foods

What foods are blue in color?

Blueberries come to mind but they're more purple than blue, but that's quibbling. Bilberries and blue potatoes and corn are others I suppose.

What other blue foods are there?

  1. Red onions will turn a shade of blue when an acid is added, but that's all I can think of.

      ditto for red cabbage

      ETA: actually, you want to add something alkaline to red cabbage to turn blue, like baking soda. I think this is true for red onions, as well.

      1. re: guilty

        You may be correct on that... I know it's a pH change that causes the color shift.

      1. re: foodieX2

        you could make blue margaritas just use blue curisal (sp) instead of triple sec

        1. re: don515

          That would be "curacao", the liqueur. One of the well-known makers is Bols.

        2. re: foodieX2

          @iluvcookies and foodieX2

          That's a good point about adding acid to certain foods to make them blue. Thanks.

        3. Bleu cheese?

          Certain edible flowers

          Blue eggs (if serving in the shells is acceptable)

          Blue foot chicken

            I like the blue eggs and chicken ideas. Thanks.

          2. Blue corn chips
            Blue tea

            1. Blue crab (although turns red when cooked...), likely some cereals, smarties/M&Ms, some parrotfish (don't know how the color changes with cooking on this one).

                Thanks, but I'm looking for non-processed foods, so things like cereals and candy would be out.

              2. not positive, but i vaguely recall hearing about some edible violets.

                  Yes. Certain blue flowers are definitely edible. Thanks.

                  1. re: ipsedixit

                    Like borage flowers - they taste like cucumbers.

                  2. re: westsidegal

                    They're purple, mostly. Pansies can approach blue, and they're tasty, too.

                    1. Several varieties of plum are blue.

                          I'm hoping for photos of what I'm imagining will be an all-blue meal.


                          1. A half pint of chicken livers in a pint container in the back of the fridge take on a lovely blue hue after about 7 months.

                                If you have a big garden there is a tree fruit called Decaisnea fargessi that is sort of blue http://en.wikipedia.org/wiki/Decaisnea

                              2. Ling cod is a lovely shade of blue when raw but I don't think it retains its color when cooked.

                                Black rice turns an interesting shade of blue/purple when cooked, especially if you stir in some coconut or other milk to spread the color.

                                1. Curious to know why you need blue foods...

                                    My avatar is losing its vibrant hue.

                                  2. Blue Jello!

                                    A word of caution (and looking back at it, humor).
                                    When blue jello first came out, I made a dessert with blue jello and cool whip. The blue jello dessert looked beautiful and delicious, I thought. Unfortunately, about the same time, we started using the cleaner that turns the toilet bowl water blue.

                                    The kids took one look at the blue jello dessert and said, GROSS! and wouldn't even try it. Oh well, I thought, all the more for me.

                                      theres a drink called the tidy bowl with the above-mentioned blue curacao and other booze with a couple of raisins as garnish for effect - along the same lines.

                                    2. If "foods" allows for drinkables: Bombay Sapphire gin is
                                      blue and could be used for, e.g., blue martinis before the
                                      themed meal.

                                      Otherwise ... good luck on this one, which the Romans tackled 2,000 years ago -- the racing chariots had different team colors, and the winning owner dinner had to do a victory dinner all in that color. Today we might try mostly white/pale foods, but trim with blue flowers & the like, use blue tablecloth, dishes, etc.,then go with deep blue LIGHTING throughout the meal!

                                        Bombay Sapphire is in a blue bottle, but the gin itself is clear.

                                          I think that the gin looks blue under certain kinds of light, like blacklight.

                                            That might be the trick... Serve all white foods, but with a black light!

                                            1. re: iluvcookies

                                              It's the quinine in the tonic water that fluoresces under UV light, not the gin.

                                                  Yep! Love gin and tonic under black light- freaks people out a bit though :)

                                        2. This is for those of us from Toronto. Blue Jello made in the Toronto Blue Jay Jello mold.

                                          Unfortunately I don't have a photo of the fabulous final creation but...

                                            I'm sorry, but Jell-O (though I love it madly) qualifies as processed, which won't cut it for purposes of my request.


                                          2. Blue foods are on the supermarket shelf next to the foods that rhyme with "orange".

                                            1. Other than edible flowers, truly blue food is essentially all unnatural. I remember hearing back in the 70s about some studies which showed that people tend to avoid blue food instinctively when given the choice.

                                              You could make blue gel or pudding using raspberry flavoring and natural blue food coloring (if indeed there is such a thing) with gelatin or some less processed agent- agar agar or rennet puddings come to mind, perhaps even chia seeds which are reputed to form a sort of pudding when left overnight in liquid. I've been meaning to try the chia thing myself.

                                                While night fishing in Key West a coupla months ago, I felt something kinda sucking on my right foot. I turned on my flashlight to discover an octopus trying to eat me. It was quite blue.
                                                I don't know who was startled more, but I tried to catch him as he scuttled under a rock. Had I been successful, he certainly would have been food and I think, quite natural.

                                              2. Oh! I just remembered, during the Minnesota State Fair, the seed artists use poppy seeds for blue... I can't imagine what food you'd have that you'd want to absolutely bury in poppy seeds, but I just thought I'd throw that out there...


                                                1. Found this violet sugar. http://www.albertyferranadria.com/eng...

                                                  Just an FYI. I made violet jelly one spring, and while the infusion was very violet colored, the resulting jelly was very pale. Plus, it had no flavor. Just tasted like sweet gelatin. Will never make again, as the picking of the tiny flowers was a PITA for such a disappointing end product.

                                                  Maybe you could make a very strong, concentrated violet infusion and use it to tint something.

                                                  Also, there is a drink called The Blue Devil.

                                                  1. Surprised nobody's mentioned blue grapes yet.

                                                    1. Purple sweet potatoes are often closer to blue than purple after boiling and mashing. The difference might be caused by variation in ripeness, but I'm really not sure.

                                                      1. Does purplish count? Maybe purple cabbage (the color may run blue in a slaw) or eggplant?

                                                                  This is why sticking plasters used in commercial kitchens are blue. Easier to spot in the risotto!

But I'd always been partial to fish eyeballs as we normally have those in Singapore fish-head curries.

                                                                          1. re: mrbigshotno.1

                                                                            I see that these fruit are eaten whole by cassowaries, Woompoo pigeons and Spectacled flying foxes, which pass the nut undamaged. "Woompoo pigeons" and "Ispedixit" passing the nut together? I'd be interested in the fight between those two for the big blue fruit...

                                                                            1. re: Servorg

                                                                              Actually they probably do. If it is like most of the other members of the genus the seeds are quite hard. Thew seeds of Eleaocarpus ganitrus commonly called rudraksha, are used throughout India and the pacific as beads. Oh and two more things. The tree isn't closely related to Qandog either (Quandog is a member of the sandalwood genus, this plant is in a family of it's own the Eleaocarpacae) and that blue color would not translate to food since it actually isn't caused by a pigment (it's actuallytechnically iridescence cased by variation in the cell walls that bounce light back at a specific wavelength. crush the fruits and the blue color dissapears.

                                                                          2. See the photos of the 2 Paloma's Gelatinas posted by Melanie Wong, especially the side view:
