I need a "blue vegetable" for a rainbow platter. I am using eggplant for the purple, unless there is another purple one (?) that I can substitute and then use the eggplant for the blue color?
Alternative, is there a vegetable I can dye blue with food coloring?
This is for a Fairy party for my 5-year-old twins -- THIS SATURDAY 3/22 -- HURRY!
