• raw tomato (cooked is fine)
• natto (I tried, I really did)
• oysters (must try again; haven't tried since I was a kid)
• cheese-flavoured chips, twisties, etc.
• pumpernickel bread (I could probably acquire the taste, though)
• strongly flavoured fish
• rollmops (betraying my heritage, there)
• fruits that are too tart (raspberries, grapefruit, etc.)
  • rhubarb (eugh! I have bad memories from when I was a kid. I tried it again recently, and I still hated it. It's just not worth it to me to try to like it.)

Foods I didn't like when I was a kid, but do now:

• mushrooms
• pumpkin
• broad beans
• scallops
• caraway seeds/bread/cheese
• balsamic vinegar
• bubble n squeak
• peas (well, I'll tolerate them, anyway)
• pistachios
  • they're actually really good when not smothered in salt

Foods I always liked even though every other kid seemed to hate them:

• brussels sprouts
• beetroot
