Angel Biscuits

1 pkg dry yeast (2 1/2 tsp = 1 pkg yeast)
1/2 cup warm water
5 cups flour
1 teaspoon baking soda
2 cups buttermilk**
3 Tablespoons sugar
1 Tablespoon baking powder
1 teaspoon salt
1/4 cup + 2 Tablespoons shortening

Dissolve yeast in warm water, let stand 10 minutes.
Sift flour, sugar, baking powder, salt and soda in large bowl.
Cut in shortening.
Stir in buttermilk and dissolved yeast mixture until moistened. Roll out on floured surface, being careful not to over handle the dough. Cut into biscuits and bake in greased pie pan at 400 degrees for 15 minutes.

*Dough can be stored in covered plastic container for up to one week.

**I usually use powdered buttermilk, follow directions on the can. Mix the dry buttermilk in with the dry ingredients and then add the water with the yeast mixture.
