I don't remember ever really "hating" any food, much less getting over it. I've always liked pretty much everything, and those things I wasn't particularly fond of (few) I still don't care for. I guess it helped that preferences were always taken seriously, and we were never forced to eat anything we didn't care for, so long as we had genuinely tried it.
hmm this is hard but I guess the only thing I can think of is stuffing I hated it and now I will eat it of course with turkey and mashed potatoes and lots and lots of gravy
But to be honest I liked a lot of foods when I was little compared to now, now I hate everything
I never cared for seafood when I was growing up. Probably because my father is allergic to it, so we never really had it. Now it's probably my favorite thing to have when I eat out!
As a kid I hated sushi, mustard, mushrooms and pickles with a passion but now I put pickles, mushrooms and mustard on every burger I have. I'm still not a huge fan of sushi but I will eat it.
