Buttermilk Biscuits - Southern

"This recipe comes from "Baking" by Dorie Greenspan, a fabulous book. I have been doing a lot of research on flour and for biscuits the consensus is use White Lily flour.

The dough can be made, wrapped air-tight and frozen for up to 2 months. If you like a crisper edge, do not let the baking biscuits touch. If you like a softer edge on the biscuit, place the biscuits on the baking tray touching each other...."
