The most disgusting type of cheese I ever ate was Cacio Marzu from Sardinia(Italy). A Pecorino type of cheese in which larvae are allowed to develop, which eat, digest and defecate the cheese, transforming it in a creamy and very piquante tasting cheese.
It tasted delicious and I wished that nobody had told me the story behind it. Maybe one shouldn't always exactly know what he is eating.....
