 That's the great thing about it. It's unlimited of what you can do with the crust. I agree with you, and I love the idea of cardamom. It's warm and has that je ne sais quoi. You can't put your finger on cardamom, but, oh, it tastes so good. I actually think cinnamon would work. We're having a bit of a cinnamon renaissance, I think, in this country because everyone has begun seasoning their coffee.
