Can't think of anything.
I never really liked artificial fruit flavors, etc, probably because they weren't part of my regular diet as a child in Europe. I was given a lot of fresh veggies and organ meats, although I drew the line at lamb brain and raw oysters. Gross texture! Just give me the shell water with lime juice and keep the brains away from me. Ugh.
I still love cotton candy - pure sugar with a little blue and pink artificial coloring is fine
