Coconut Flour Cookbook
I have a good cookbook I found on Amazon (around $10):
Cooking with Coconut Flour by Bruce Fife
His main focus is gluten-free, so some of the recipes have some corn meal or sugar, but many don't. He uses a lot of almond flour as well. Great recipes for bacon & cheese muffins, chicken pot pie, etc. There are definitely enough primal-friendly recipes to make it worth the price.
He also has another and I believe it's just a general coconut cookbook. I was planning on picking up both today.
