Sift the dry ingredients together and cut in the lard or shortening. Add enough buttermilk to make a soft dough. Pinch off about a lemon sized ball of dough for each biscuit and pat out with your hands. Bake for 12 – 15 minutes at 450 degrees or until the tops are golden brown. Remove the biscuits form the oven and rub butter on the tops of the hot biscuits to coat.
