2 c. flour
1 c. whole wheat flour
4 1/2 tsp. baking powder
2 tbsp. sugar
1/2 tsp. salt
3/4 tsp. cream of tartar
3/4 c. butter
1 egg, beaten
1 c. milk

In a bowl, combine the flours, baking powder, sugar, salt and cream of tartar. Cut in butter until mixture resembles coarse corn meal. Add egg and milk, stirring quickly and briefly. Knead lightly on floured board. Roll or pat gently to 1-inch thickness. Cut into 1 to 2 inch biscuits. Place in a greased 10-inch iron skillet or in a 9-inch square pan. For crusty biscuits, separate on a cookie sheet. Bake at 450 degrees for 12 to 15 minutes.
