Heat oven to 450 degrees. In a large bowl, combine flour, baking powder and salt. Using a fork or pastry blender, cut shortening into flour until consistency of coarse meal. Add milk; stir with fork until mixture leaves sides of bowl and forms a soft, moist dough. On floured surface, toss lightly until no longer sticky. Roll out 1/2 inch thick; cut with a 2 inch floured round cutter. Place on ungreased cookie sheet. Bake for 8-12 minutes or until light golden brown.
