Notes: A food processor can be used to cut butter into the dry ingredients. Place dry ingredients into the work bowl of the food processor, and pulse until combined. Add cold butter, and pulse until mixture is crumbly and the largest butter pieces are pea-size. Transfer to a large bowl before adding buttermilk.
Biscuits can be baked touching if you want a softer biscuit. If you like a biscuit with crispy edges, bake about 2 inches apart. Biscuits that are touching will take longer to bake, and biscuits with space between them will bake faster.
