I'm (mostly) with Elynor. Bananas are OK just past the green stage. Not OK mushed and made into bread, icecream, pudding, etc. Banana flavouring is truly ick. Worse than watermelon gum, and that stuff is nasty!
Strawberries, ditto. I'll only eat them fresh.
For whatever reason, raspberries, apples, other stuff is just fine in jam, cakes, sauces. I never outgrew the picky eater phase, I guess.
