Gravy is a savory sauce made with meat drippings, flour, and milk or cream. While ham and beef are not the best meats to use for gravy due to their salty or fatty qualities, bacon is a great alternative. Poultry, particularly turkey, is also a safe and delicious choice for gravy. The earthy flavor of dark meat enhances the richness of the sauce. So, save those turkey drippings for a tasty breakfast or sandwich.
