There's only one food I will not eat, hate, doesn't matter how you cool it, green/string beans. Something about the texture. I will cook them fresh and get lots of compliments, taste them while I'm cooking to make sure they're ok, spit it out and wash my mouth out. Always hated them since day one, it's the only picky eating thing I never grew out of and I wasn't a very picky eater as a kid. Everything else is in play...raw oysters, squid, fish, all kinds of sushi, all kinds of veggies and fruits, game meats, stinky cheese. I'm a pretty adventurous eater overall or at least open to trying things.
I dont like pickles/cucumber. Some how the combination of crunchy/slimy texture doesnt sit with me.
I try them frequently though. I am all about reaffirming that I dont like them.
