To make an easy ham gravy, melt 1 stick of butter in a pan in which a ham was cooked, whisk in 1/4 cup of flour, and continue adding flour until a smooth paste results. Cook over medium heat for three minutes, adding 4 to 6 cups of whole milk.
When adding the milk, whisk the entire time to avoid lumps in the gravy. It should have a deep golden color once finished. Season the gravy with salt, pepper and herbs. If no ham juices are available, use bacon grease instead. A tablespoon of drippings typically yields 1 cup of gravy. Because the juices from a cooked ham are involved, the recipe for the ham affects the taste of the gravy. The gravy may be poured over the ham itself, mashed potatoes or biscuits.
Alternatively, bring the ham drippings to a boil. In a separate bowl, mix 3 to 4 tablespoons of flour with cold water until a runny paste forms. Pour the mixture into the boiling ham drippings a little at a time, whisking the entire time until the gravy has thickened. Add salt and pepper to taste. Use a strainer if any lumps occur in the finished gravy.
