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.

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

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

          @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.
