I took a class last night where we cooked Duck. I liked the taste, I liked the sauce, but the texture made me want to gag.
I second whoever said they don't like strong smelling, oily fish or Bivalves. I also enjoy well prepared scallops.
The night before my appendix went bad on me I made a huge batch of chewy buttery oatmeal cookies. For many years after that I could not eat that kind of oatmeal cookie at all. I could only eat the dry, cinammony ones. After about 15 years, my body gave up that association, though they're still not my favorites.
