Preheat the oven to 375 degrees F. In a mixing bowl, combine the dry ingredients and blend
in the shortening with your fingers or a fork, until the mixture resembles coarse crumbs. Add the buttermilk a little at a time and, using your hands or a fork, work it in just until its thoroughly incorporated and you have a smooth ball of dough. Do not overwork or overhandle the dough. Lightly floured surface, roll out the dough
with a rolling pin
to a circle about inches in diameter, 1/2-inch thick. Using a small round cookie cutter
or the rim of a shot
glass, press out twelve 1-inch rounds. Place the biscuits
on a baking sheet and bake until golden brown, about 15 minutes.
