Angel Biscuits
2 packages dry yeast
1/4 cup warm water (105 degrees to 115 degrees)
2 cups buttermilk
5 cups all-purpose flour
1/4 cup sugar
1 tablespoon baking powder
1 teaspoon baking soda
1 teaspoon salt
1 cup shortening
Combine yeast and warm water; let stand 5 minutes. Add buttermilk to yeast mixture, and set aside. Combine all remaining ingredients except shortening in a large bowl; cut in shortening with a pastry blender until mixture resembles coarse meal. Add buttermilk mixture, stirring with a fork until dry ingredients are moistened. Turn biscuit dough out onto a lightly floured surface, and knead lightly 4 or 5 times. Roll dough to 1/2-inch thickness; cut with a 2 1/2-inch biscuit cutter. Place on lightly greased baking sheets. Cover and let rise in a warm place (85 degrees), free from drafts, for 1 hour. Bake at 450 degrees for 10 to 12 minutes or until browned.
