Buttermilk Biscuits

Ingredients
4 C flour
2 tsp salt
1 Tbls baking powder
2 tsp baking soda
1 C shortening, cold, cut into ½" pieces
1½ cups buttermilk, plus additional for brushing

Directions
Preheat the oven to 375° F.

Sift together the flour, salt, baking powder, and baking soda. Cut in shortening using pastry blender or a stand mixer fixed (with dough hook) until mixture resembles coarse crumbs. Add 1 cup buttermilk, mixing just until a sticky, but workable dough forms. Add more buttermilk if needed.

Turn the dough out onto a floured surface. Gently fold over itself 3 or 4 times to create layers. Press dough  to 1½" thick; cut with a floured biscuit cutter. Lay the biscuits on ungreased baking sheet; brush tops with
buttermilk. Bake 20 to 25 minutes until risen and golden brown.
