2 c. flour
1 1/2 tsp. baking powder
1/2 tsp. baking soda
1 tsp. salt
1/2 c. shortening
2/3 c. buttermilk or 2/3 c. milk plus 2 tsp. white vinegar

Mix all dry ingredients with shortening. Add milk. On a floured surface, roll out until approximately 1/4-inch thick. Cut with a floured cutter. (I use a drinking glass because it's easier and less messy.) Place on an ungreased cookie sheet. Cook at 450°F for 10 to 12 minutes.
