I have never been able to eat raisins without feeling grossed out. Craisins I tried recently and liked, but both black and white raisins I find revolting. Same with olives, which garners me odd looks considering I'm Italian. I mean, olive oil is awesome, but that's it. I've never liked cow's milk (even before I became allergic to it), but I do love cow's cheese (fortunately the allergy passed after about a decade). Overcooked vegetables make me gag, as do some canned and frozen (spinach and green beans come to mind) which I would otherwise enjoy if they were made from fresh. Yams...I never liked yams/sweet potatoes all that much, although on occasion I've enjoyed a homemade dish. Beef stroganoff used to make me sick as a kid, I didn't even need to eat it. The smell alone would repel me from the house. There are some things, like brains and kidneys, that I have only had after preparing myself and didn't care for, but would try again if I knew it was prepared by someone who knew what they were doing. All the other really "exotic" things I've tried (there's unfortunately not been many) I have liked. There's an Asian grocery store near me that carries some stuff I'd love to try (namely seafood) but I'm afraid to because the two separate times I have purchased frozen prepackaged seafood from them I got food poisoning. I still want to try durian though.
Oh, and divinity. My dad once dreamed of going into the candy business so he would make a recipe over and over trying to get it perfect. I never got tired of the fudge, but if I so much as see divinity nowadays I have to suppress a gag reflex.
