I don't like fennel seeds or caraway seeds, and I can only tolerate stuff like clove, allspice, and anise in small amounts. The thing I really dislike, are curry powders. The smell of those things almost makes me vomit, and it lingers like crazy for hours if not days when you cook with it in your house. I have to scrub all my pots and pans multiple times to get that smell out of them, not to mention opening my windows and Febreezing everything. It's terrible.
