Not much I wont eat or try.
However, try as I might, I am not a fan of raw, unprocessed tomatoes. Like cherry tomatoes in a salad, for instance.
If they are done really "well" like chopped and skinned and de seeded on a bruschetta with dressings etc, fine, and of course cooked or as a sauce base or flavour, fine. But just to eat a raw tomato I can't do unless it were a bush tucker trial! Don't like the horrible slimy "savoury fruit" things.
On that theme I'm not a fan of savoury fruit in general, which leads to fruit and meat combos. Mango chicken. No. Pineapple on a pizza, just about okay. Raisons in a tagine, just about okay. Berries in salads with ham, not great. And so on so forth. Of course I avoid the bit I don't like if in company.
Can't think of much else. Things which would make some people flinch like raw beef (tartare etc), tripe, nose to tail stuff in general, capers, posh shite, strong flavours, exotic stuff, couldn't care less. I blanched slightly at some langoustines with the roe attached when I ate at St Johns in London when I was pregnant, mainly because I felt I was eating a mother and baby but I ate them anyway and they were fabulous.
So not much really. But tomatoes, gawd.
