Google is a pretty useful tool, in my opinion, I'm not being hostile by suggesting it.
You never mentioned that you had even tried to look on your own for a cookbook, why should I assume that you had attempted a Google search?

Googled it.
Good luck in finding what you need. There are tons of online recipies you might want to look in to trying, too (to me, they're easier to follow than a cookbook, plus they're free!).
