Potato Biscuit Recipe
Original recipe makes 8 biscuits
2 1/2 cups all-purpose flour
2 tablespoons baking powder
1 teaspoon salt
1/4 cup sugar
1/4 cup butter or margarine
1 1/2 cups Washington mashed potatoes
1 egg, beaten
1/3 cup cold water
1/3 cup milk
2 tablespoons milk, or as needed
1. Preheat the oven to 450 degrees F (230 degrees C).
2. In a medium bowl, stir together the flour, baking powder, salt, and sugar. Cut in butter, until pieces of butter are no larger than peas. Use a fork to stir in mashed potatoes, breaking them up into chunks. Make a well in the mixture, and pour in egg, water and milk. Stir into a loose dough using the fork.
3. Turn dough out onto a floured surface, and knead for 6 or 8 times so the dough holds together. Pat the dough out to about 3/4 inch thickness, and cut into circles with a biscuit cutter or drinking glass. Place biscuits onto an ungreased baking sheet. Brush the tops with 2 tablespoons milk.
4. Bake for 15 to 20 minutes in the preheated oven, or until bottoms are golden.
