Gravy is a sauce, made often from the juices that run naturally from meat or vegetables during cooking. In North America the term can refer to a wider variety of sauces. The gravy may be further colored and flavored with gravy salt or gravy browning or ready-made cubes and powders can be used as a substitute for natural meat or vegetable extracts. Canned gravies are also available. Gravy is commonly served with roasts, meatloaf, rice, and mashed potatoes.
