x-post: What are your favorite cookbooks?

I'm working on the registry and FH and I only have 2 cookbooks. LOL We'd like to register for a bunch but have no idea where to start. FYI: We are both vegetarian but we do eat fish and shellfish.

As of right now we have 2 seafood books, I registered for pasta, soup, and vegetarian book out of the William-Sonoma Food Made Fast collection.

Please post your favorites!

(I'm gonna be hungry.)
