This is my favorite biscuit recipe. I don't recall where I got it, but I've used it for the last 25 years. Very rich, tender and flaky!

3 1/2	Cups	Unsifted flour
2	Tsps.	Baking powder
1/4	Tsp.	Salt
1	Tbsp.	Sugar
1	Cup	Butter flavored shortening
1/3	Cup	Warm water
1	Pkg.	Dry yeast
3/4	Cup	Milk - at room temerature

In a medium bowl, combine 3 cups flour and dry ingredients (except yeast). Cut in shortening to rememble course crumbs. Soften yeast in warm water. Stir in milk and yeast mixture with hands. Sprinkle a board with remaining 1/2 cup flour. Turn out dough on board and knead a couple of times. Pat out to 1/2" thick. With a large knife, cut dough into 9-12 squares. Place 1-inch apart on greased baking sheet. Prick tops with fork. Set aside in warm place for 20 minutes. Heat oven to 400°. Bake until golden brown (8-12) minutes - cool slightly, and brush tops with melted butter if desired.
