Preheat oven to 400 degrees F (205 degrees C). Grease a baking sheet.
Combine flour, baking powder, and salt. Cut shortening in until mixture has a fine crumb texture. Stir in milk with a fork to make a soft dough. Knead 8 to 10 times, and then roll out to a thickness of at least 1/2 inch. Cut into rounds with a cookie or biscuit cutter. Place on cookie sheet, and allow to rest for a few minutes.
