I like liver but only if it's well done. I like kidney also. I've had cow's heart once, years ago. Thought it was nice but very strong taste. Love sprouts also. Don't mind marmite but don't actively purchase or consume it. Love olives, especially black, but a lot of people hate them.
I think pineapple and grapefruit are the only fruits I hate.
I hate raw celery but don't mind it in stews and soups.
Growing up, used to hate cabbage and turnips, absolutely would not touch them, but quite like them now.
Tried anchovies from a tin once out of curiosity as I heard it mentioned on US TV and movies etc but I think I spat it out straight away - wasn't expecting it to be as salty (or hairy!) as it was. Think I got a fright, maybe I might like it now.
