Derby Breakfast Yeast Biscuits
1 cup warm buttermilk
Dissolve yeast in warm buttermilk; set aside. Sift soda, salt, sugar, and flour into a bowl; cut in shortening. Add yeast mixture; stir until blended. Knead and roll 1/2 inch thick. Cut with biscuit cutter; dip in melted butter and place in a greased pan. Let rise 1 hour. Bake at 425 degrees for 12 minutes.
If biscuits are made for future use, bake only 6 minutes and brown when reheating.
