A combination that the vast majority of my fellow humans delight in, but that I find absurd: chocolate & nuts. As a child, I used to read the fine print on the wrapper of a candy bar to make sure I was not about to be confronted with that.

I read, several years ago, that some standards commission of the EU had caused outrage in Italy by banning maggoty cheese. My immediate thought was that the idea of eating maggoty cheese did not appeal to me, but I would be happy to chew up a whole mouthful if I might thereupon spit it in the face of a bureaucrat who couldn't mind his business.
