What's in your "secret" recipes?

A friend was telling me about another friend who won’t divulge her recipe when asked. This got me thinking. How do I feel about “secret” recipes? I am always happy to share my method and ingredient list, unless I bought it. That’s when I laugh and say, “It’s a secret.” Now you know my secret.

What do you think of the idea of a "secret" recipe? Do you share your recipes when a friend asks? Post your comments here.
