Blend dry ingredients. Cut or pinch in the butter until it's in pieces no larger than pea sized.

Place bowl in freezer. Preheat over to 450F.

Remove bowl from freezer after 15 minutes. Stir in buttermilk, then fold over dough 6-8 times (as little as possible). Roll to 1/2" thick and cut biscuits; place touching each other on baking sheet. Bake 15 minutes or until starting to brown.
