Over the course of the year, I will usually buy the meals that I plan to take and try them at home. Obviously, it tastes a little worse at home than on the trail, but it does give me a good idea on what I like and don't like. Everyone likes different stuff, so even though you don't like that one particular one, doesn't mean that others won't.
Let me give you an example...I don't like the taste and smell of coffee. My guess is that I am alone in this. Well, I know some who share this distaste, but we are a very small minority.
I've taken a vow of poverty. To annoy me, send money.
