Hard to say. I tend to opt for safe things most of the time. Twice as a child I was conned into taking a spam fritter under the belief it was fish. I like battered fish. It was not fish. I do not like spam.
Texture-wise, I cannot abide kidney. Used to love steak and kidney pies but something changed when my adult teeth came in.
Thirdly, I still have flashbacks to a serving of whitebait I ordered out of curiosity in a restaurant one time. They didn't taste terrible that I remember. Just... whole little fish cooked and to be eaten whole. Never again.
And then there was the case of the Kit-Kat that I was eating blind, piece by piece from my coat pocket, and one of the pieces was hard and unpleasant. I am still not sure there wasn't something else in my pocket that I grabbed and ate by mistake, but that's pretty up there.
