@missyb, I use a mild sausage, drain the grease, then stir in about 2 heaping tablesppons of flour. I remove it from the heat and the work the flour into the sausage with a fork like @NUNYA said. Then add 1 cup of milk, work it into the sausage, and put it on medium heat, stirring constantly. Once it starts to thicken, add another cup of milk, and then stir until it thickens. Add 1 teaspoon salt, ½ teaspoon pepper, 1 teaspoon thyme, and ½ teaspoon sage. A little garlic powder’s good too. Stir it all in, and let simmer for about 2–3 minutes. Add more milk if it gets too thick. Serve over biscuits.
I like to use Field’s Ham Sausage if I can get it.
