There are few foods available to me in day to day life that I dislike (and that includes my few European and Asian travels, and friends who were from those areas and made foods that many of my U.S. friends wouldn't eat). Bugs, durian, stinky tofu aside, these are things I haven't been pressed to try and wouldn't care to. I'm not one of those people who gags and makes a fuss when I don't like something, as a general rule, I can eat things I don't like. And my few dislikes are:
Corn meal. Corn bread, tamales, sckanze, polenta. I love, and I do mean love, corn, but for some reason am not crazy about corn bread/mush/grits in its many forms. Again, I can eat it, just don't like it.
Milk. Again, I like every form of milk I've ever had, just not a glass of milk. Go figger. Seriously, when I was a child my friends' mothers and mother's friends would give me no end of grief because I simply didn't want to drink milk, and could live forever without breakfast cereal. They'd tell me I'd better drink my milk or I wouldn't grow strong and tall. At 55 I'm 5'9" and show absolutely no signs of bone loss.
There are a few things I don't care for in certain preparations, it is usually a texture thing. But very little that I dislike actively.
I am with you there. I use milk in cooking and even eat cereal, the milk left in the bowl just goes down the drain. I rarely buy milk anymore, I keep powdered around for cooking. I just got tired of throwing away spoiled milk.
