1 package dry yeast
1/4 cup warm water
2-1/2 cup flour
1/2 teaspoon baking soda
1 teaspoon baking powder
1 teaspoon salt
1/8 cup sugar
1/2 cup shortening
1 cup buttermilk
Dissolve the yeast in warm water and set aside. Mix the dry ingredients in the order given (flour, baking soda, baking powder, salt and sugar), cutting in the shortening as you normally do for biscuits or pie dough. Stir in the buttermilk, also the water-yeast mixture. Blend thoroughly and the dough is ready to be refrigerated in a large covered bowl or made into biscuits. When you are ready to make the dough into biscuits, turn it out onto a floured board and knead lightly as for regular biscuits. Roll out and cut with a biscuit cutter and place in a greased pan. Let the biscuits rise slightly (if the dough is cold, it will take a little longer for them to rise than when first mixed) and pop into a 400 degrees oven until lightly browned (about 20 minutes).
