I can't believe some of the things people don't like.
Turkish delight (including rose flavoured), cauliflower, sprouts, mushrooms, peanut butter, marshmallows (*), broccoli, onions, garlic, marzipan, tomatoes, liquorice, cabbage (**), bananas, mango chutney, olives, pickled 'anything', chutneys in general, pancakes, cinnamon, christmas pudding, warm cookies, mint chocolate, nuts, parsnips, pine nuts, grapefruit, donuts, sauerkraut, and LOADS of other things mentioned here are absolutely delicious.
(*) I only eat vegetarian ones.
(**) Particularly fancy varieties
The only thing I've tried recently which I couldn't eat were Aldi oven chips. Even though I shop at Aldi regularly and buy plenty of their goods, the oven chips were foul.
