Gravy is a sauce, made often from the juices that run naturally from meat or vegetables during cooking and often thickened with wheat flour or cornstarch for added texture. 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.
