Before you begin, make sure all ingredients are ice cold, and make the biscuits quickly and get them into the oven before they heat up. That is the secret of a tall and flaky biscuit. Of course, not handling them too much and the addition of cream of tartar is important, too. I use a parchment lined 9X13 metal baking pan for my biscuits. Preheat the oven to 450 degrees. Bake about 15 minutes until golden brown or a little darker, like mine. This recipe makes 6 large biscuits.
