Making white gravy is simple and delicious. Melt four tablespoons of butter in a pan and add four tablespoons of flour. Salt and pepper to taste. Cook and stir until the mixture is smooth and bubbling. Stir in 2 1/2 cups of milk and heat until boiling, stirring constantly. Let the gravy boil for one minute to cook out the raw flour taste and enjoy your gravy over some piping hot biscuits.
