I have this insane craving for brussel sprouts. I'm about the only creature in the Universe who likes and craves brussel sprouts. Plain boiled, no sauce, dip or any other kind of flavouring on them. Sometimes, I'll put a little mayonnaise on them, but I usually eat them just by themselves.
I also like chicken marrow. Every time we get chicken, I'll eat the meat, then hack up the bone with my teeth to get at the marrow inside. Bungo always looks at me sideways when I have a plate full of chicken bone splinters.
Pork liver. Especially, unseasoned, thrown into Hot Pot and eaten plain.
Chicken hearts. Jelly-fish. Though I don't have these very often.
