I don't mind the flavor but I hate that I'm an onion/garlic sweater. For days after eating garlic or most onions, I stink so badly no perfume or deodorant or antiperspirant can control it. As a girl growing up, it was a real problem, and once I was old enough to do my own cooking I started leaving them out, or using sweet onions when they were too important to exclude.

I'm also capsaicin-sensitive, like major ass-bleeding bad, so I minimize spicy peppers and use bell peppers plus black pepper/wasabi/horseradish/ginger for spice. If it's not my cooking I get "Mild" and do the best I can with it.
