Melt the butter in a sauce pan on medium heat. Add the sausage & garlic sautéing it for about 15 min. Fold in the flour whisking it until it's free of clumps. Once it's stirred in evenly add the heavy cream & seasonings. Let the sauce simmer down for about 20 min or until it becomes thickened to your liking. You can serve it over Chicken, Fish or Pork.
