Directions from https://www.tasteofhome.com/recipes/angel-biscuits/
1 package yeast
1/2 cup warm water (110°)
1/2 cup warm buttermilk (110°)
5 cup flour
3 teaspoons baking powder
1 teaspoon baking soda
1 teaspoon salt
3 tablespoons sugar
3/4 cup shortening
melted butter
Heat oven to 400°
Dissolve the yeast in the warm water and let stand 5 minutes. Stir in the warm buttermilk and set aside.
In a separate bowl, sift together the flour, baking powder, baking soda, salt, and sugar, then cut in the shortening until it resembles course crumbs.
Stir in yeast mixture.
Turn out onto a floured surface and knead gently 3-4 times. Roll out to 1/2 inch. Cut with a biscuit cutter and place 2 inches apart on greased baking sheets.
Cover with kitchen towels and allow to rise until doubled in size, about 1 hour.
Bake for about 12 minutes, or until light golden brown. Lightly brush the tops with melted butter.
