Love the smell of liver and onions frying up, but can't stand the taste of liver. Pickled beets took awhile to grow on me, I like them but my wife really likes them (I really like the pickled eggs we do in the same jar as the beets. Organ meats just aren't my style or taste. Love seafood - except oysters, just can't get into them. Tried over the years, fried, in stew, raw, whatever and just never cultivated a taste for them. Mussels, clams, abalone, seafood in general, everything else is great, but not oysters.
Spent 26 years in the USAF and traveled a good bit and would try most things once. Somethings absolutely not. Was stationed with a special team in Egypt to help them open a base that was getting F-16's for a night fighter squadron. Got invited to one party and they passed around a huge bowl of (you just reached in and popped them in your mouth like grapes).... sheeps eye balls! Nope, did not do that.
Also won't eat eel, it might be a great delicacy in Japan, but not for this kid, had it once, will; never eat it again.
