Note: I have had this recipe for a few years. I believe it was originally from a Southern Living magazine. This makes enough for 1 9-inch deep dish pie shell.
1 1/4 cups all-purpose flour
2 tsp baking powder
1/2 tsp salt
1/2 cup shortening
1/2 cup sour cream
In a bowl, stir together the flour, baking powder, and salt.
Using a pastry blender or two knives, cut the shortening into the flour mixture until mixture resembles small peas. Add the sour cream, stirring with a fork until combined.
Gently gather the dough into a flat disc and wrap in plastic wrap.
Chill dough at least 1 but up to 24 hours.
Roll out on a lightly floured surface.
