Directions

1. Dissolve yeast in warm water. Allow to stand until mixture is frothy.
2. In a large bowl, whisk together flour, sugar, salt, baking powder, and soda. Add shortening and work until crumbly. Mix in yeast mixture and buttermilk. Store, well covered, in a greased bowl in the refrigerator. Don't worry if it is a little sticky; it will firm up as it chills. Dough can be stored up to 2 weeks.
3. When ready to make rolls, take out amount needed. Turn dough out on a lightly floured surface, and knead for 2 or 3 minutes. Roll out, and cut rolls. Place in greased muffin cups. Let rise for 30 minutes.
4. Bake in a preheated 400 degrees F (205 degrees C) oven for 15 minutes, or until golden brown.
