Buttermilk Biscuits

4 cups all-purpose flour
1 1/2 tsp. salt
2 1/2 tsp. baking soda
1 1/2 tsp. baking powder
1/3 cup shortening
1/3 cup cold butter, cut into pieces
1 1/4 cups buttermilk

In a large bowl, combine all the dry ingredients and stir together.  Add the shortening and butter. 

With a pastry blender or fork, cut in the shortening and butter until the mixture resembles coarse crumbs.  Pour in the buttermilk and mix gently with a fork until just combined.  The biscuit dough will be sticky, not overly dry or crumbly.  Lightly flour a clean surface. 

Turn dough out of the bowl and roll to a 1/3-3/4 inch thickness, depending on how thick you'd like your biscuits to be.  Cut rounds with a biscuit cutter and place them in a baking dish or on a cookie sheet.  Bake for 11-14 minutes or until golden brown.  (Watch them, mine were done at 10 minutes.
