Sour Cream Cheddar Biscuits

2 c. flour
4 1/2 tsp baking powder
1 tsp salt
3 tbsp margarine or butter
1/2 c. grated cheddar cheese
3/4 c. milk
1/3 c. sour cream

Mix flour, baking powder and salt together. Add margarine and blend well with pastry blender until mixture is fine crumbs. Add the cheese, ensuring that it is evenly distributed. Add milk and sour cream all at once; stir. Either drop by spoonfuls onto ungreased baking pan or place on a floured surface, pat down slightly and cut. (We like to top with additional grated cheddar cheese.) Bake at 400 for 15 minutes. Yeilds approximately 10 2" biscuits.
