Southern Buttermilk Biscuits

2 c flour
3 tsp. baking powder
1/2 tsp. salt
1/3 c shortening
7/8 c buttermilk

Sift dry ingredients thoroughly. Cut shortening into dry ingredients until it resembles rice. Make a well in the center and pour in the buttermilk all at once. Stir vigorously with a fork until just combined.
Turn out onto a floured surface and knead a few times. Roll out to 1/2" thick and cut as many biscuits as possible. Trimmings may be clustered together and recut. Place biscuits on a greased baking sheet and brush with butter or milk.
Bake at 450 degrees, 12 minutes. Serve hot from the oven with butter, preserves, or gravy.
