2 cups buttermilk
1 package yeast active dry
1 teaspoon baking soda
1 teaspoon salt
1 teaspoon baking powder
1 teaspoon cream of tartar
2 tablespoons sugar
4 cups flour
1 cup butter or margarine
Heat buttermilk to lukewarm and add yeast; stir until dissolved. Cool. Mix and sift dry ingredients into bowl. Cut in butter or margarine until size of small peas. When buttermilk is cool, mix with dry ingredients. Put in covered container and refrigerate until ready to use. Roll dough and cut into biscuits. Let rise 20 to 30 minutes before baking in a preheated 450° F oven for 10 minutes.
Note: A most unusual recipe. Dough keeps covered in the refrigerator for at least 5 days.
