Turkey Gravy is an “eyeball” thing. Please note that the measurements in this recipe are estimates.
If you are “measuring” your ingredients, measure your pan drippings. If you have about 4 cups of pan drippings, you will need 2 tablespoons of fat and flour for every 1 cup of liquid (so 8 tablespoons of fat and 8 tablespoons of flour).
