We find that we use cayenne pepper the most in our Mexican, Tex-Mex, and Southern cooking. Just a pinch adds a sweet-spicy heat to an entire pot of beans, enchilada sauce, fried chicken, or even mac n' cheese! We also really like it in egg dishes and some dry-rubs for meat and seafood.
Cayenne also has received a lot of attention for its health benefits, and in fact it was used as a medicine before it was really considered a culinary seasoning. A diet with regular amounts of cayenne is said to have a positive affect on both the digestive and circulatory systems.
When you first start cooking with it, start off with a quarter teaspoon of cayenne for a large dish like a soup or braise, or a bare sprinkling for smaller plates like scrambled eggs. This gives you a bit of spice without feeling overwhelmed. Remember - you can always add more, but you can't take it out once it's in there!
