From: I took this recipe of an imitation KFC gravy, omitted the pepper, went for it. It was scrumptious!
1 cup drippings
4 Tbsp butter, melted
1/4 cup flour
1/4 cup of chicken stock (or substitute water and chicken bullion)
Combine all the ingredients in a small pot or skillet. Whisk together until smooth. Turn on medium high heat. Whisk as it heats up and thickens. Remove from heat just before it reaches the thickness you desire. It will continue to thicken as it cools.
