In the pan which the meat was cooked, add 1/4 cup flour to the 1/4 cup drippings already in the pan. Cook and stir over medium heat for 5 to 10 minutes or until mixture starts to brown. Add the salt and pepper then slowly add the milk, stirring constantly.
Continue cooking until gravy boils and thickens. If gravy is too thick, add a little milk. Adjust seasonings to taste.
