There's food that you detest out of bad experience, food that the very thought of revolts you, and food that other people eat that you personally can't see the point of. I'm not going to eat little slivers of raw fish. I'm not eating lamb or duck that looks raw in the middle when you cut into it (though, oddly, I'm fine with rare beef). I don't especially mind most shellfish, cockles, mussels and the like, but I don't go out of my way to try them. I'm sure snails are very tasty, but no thanks. I love a nice rare sirloin steak but I'm not going to eat that line of fat down one side. Sweet potatoes as a side dish are OK but they are not a proper spud. Maybe I shouldn't, but I cut the roe off certain fish (e.g., dabs) and bin it before cooking the fish. I love pork scratchings and even devour what are indisputably nipples in there. I've heard apocryphal tales of pigs' arseholes turning up, but in my extensive scratchings-eating experience I've never encountered one and wouldn't worry if I did. When it comes what meat I prefer, my stock answer is, I'm not fussy - just wipe the cow's arse and pull the horns out.
