Giblet Gravy is a classic Thanksgiving gravy made from the drippings of a roasted turkey and the giblets (heart, liver, and gizzard). The drippings are combined with flour to make a roux, then simmered with chicken broth and the cooked giblets until thick and flavorful. The gravy is strained to remove any lumps or solids, then served over mashed potatoes, turkey, or stuffing. This rich and savory gravy is the perfect accompaniment to a holiday meal.
