Curry, not only will I not eat it, I won't stay in the same room with it. The smell is just over the top bad.
I don't like onions, bell peppers (actually, I wont' eat them, but I will pick them out of food as politely as possible).
I have eaten things such as tripe, don't need to do that again.
One of my biggest disappointments in life is that I turned down fried caterpillars when they were offered to be in Mbare. They are their version of french fries and the woman who offered them was being nice to me. I wish I'd tried one.
