Gravy is a sauce made often from the juices that run naturally from meat or vegetables during cooking. 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.

Thickened gravy

Gravies are often thickened with a starch, starting with a roux made of wheat flour, cornstarch/cornflour, or arrowroot. The liquids from cooked meat, the liquids from dissolved bouillon cubes/stock cubes, or stock are added gradually to the mixture, while continually stirring to ensure that it mixes properly and that the thickener does not clump. In some recipes, the animal fat in the roux may be omitted as part of the base content. It may be replaced with cornstarch/cornflour alone (see cowboy roux) or is sometimes omitted entirely.

Types of gravy

• Egg gravy is a breakfast gravy that is served over biscuits. Meat drippings (usually from bacon) and flour are used to make a thick roux. Water is added, the gravy is salted and peppered to taste, and the liquid is brought back up to a boil. A well-beaten egg is then slowly added while the gravy is stirred or whisked swiftly, cooking the egg immediately and separating it into small fragments in the gravy.
• Giblet gravy has the giblets of turkey or chicken added when it is to be served with those types of poultry, or uses stock made from the giblets.
• Onion gravy is made from large quantities of slowly sweated, chopped onions mixed with stock and wine. Commonly served with sausages and mash, chops, or other grilled or fried meat cuts which by way of the cooking method would not produce their own gravy.
• Red-eye gravy is a gravy made from the drippings of ham fried in a skillet/frying pan. The pan is deglazed with coffee or water. Coffee is the traditional method. A small amount of sugar is often added also. This gravy is a staple of Southern U.S. cuisine and is usually served over ham, grits or biscuits.Fact: date=November 2008
• Tomato gravy is a gravy made from canned or fresh tomatoes, flour, and usually a small amount of fat. This is generally considered a Southern U.S. dish .
• Vegetable gravy or Vegetarian gravy is gravy made with boiled or roasted vegetables. A quick and flavorful vegetable gravy can be made from any combination of vegetable broth or vegetable stock, flour, and one of either butter, oil, or vegan margarine. One recipe uses vegetarian Bouillon cubes with cornstarch (corn flour) as a thickener (Cowboy Roux), which is whisked into boiling water. Sometimes vegetable juices are added to enrich the flavor, which may give the gravy a dark green color. Wine could be added. Brown vegetarian gravy can also be made with savory yeast extract like Marmite or Vegemite. There are also commercially produced instant gravy granules which are suitable for both vegetarians and vegans.
• White gravy (Sawmill gravy in Appalachian cuisine) is the gravy typically used in biscuits and gravy and chicken-fried steak. It is essentially a Béchamel sauce, with the roux being made of meat drippings and flour. Milk or cream is added and thickened by the roux; once prepared, black pepper and bits of mild sausage or chicken liver are normally added. Besides white and sawmill gravy, common names include cream gravy, country gravy, and milk gravy.
