Broth and gravy

Broth and gravy are both savoury liquids made by extracting flavour from food, but they are not interchangeable terms in most kitchens. Broth is generally thin enough to drink or use as a cooking medium. Gravy is usually a finished sauce: more concentrated, more heavily seasoned and thick enough to cling to what it is poured over.

The boundary is not absolute. A well-reduced broth may be served as a sauce, while an unthickened pan sauce may be called gravy in domestic cooking. Culinary language has never been entirely governed by viscosity, though viscosity remains a useful guide.

What broth is¶

Broth is made by simmering meat, poultry, fish, vegetables, grains or legumes in water, often with aromatics and seasoning. It may be prepared from raw ingredients or from cooked food, and it can be served on its own, as the liquid in a soup, or as the foundation of another dish.

Broth usually has a lighter body than stock. In modern usage, the two words overlap considerably: Chicken stock and chicken broth may be made from the same ingredients, although stock traditionally places greater emphasis on bones, connective tissue and gelatin, while broth is more likely to contain meat and be seasoned for direct consumption.

A broth intended for drinking is normally strained and skimmed. It may be clear or cloudy, depending on how vigorously it was simmered and whether the proteins were removed. A gentle simmer preserves clarity; a rolling boil turns a poultry or meat broth cloudy without necessarily making it more flavourful.

What gravy is¶

Gravy is a sauce made to accompany a principal food. Traditional British gravy begins with Roasting juices, fat and the browned residue in a roasting tin, then adds stock or water. The liquid is commonly thickened with flour, reduced to concentrate its flavour, or both. Gravy from stock is the corresponding version made without enough fresh meat juices to provide the base.

Gravy is expected to have a coating consistency. A spoonful should cover mashed potato or a slice of meat rather than disappear immediately into it. This body may come from flour, cornflour, reduced gelatin, puréed vegetables, dairy or reduction alone. The method described in Thickening with flour vs cornflour affects both texture and flavour: flour contributes a cooked, rounded taste when made into a roux, while cornflour gives a cleaner and more immediate thickening effect.

Not every gravy is brown. White gravy is made with milk or cream and a pale roux, while American sausage gravy is a seasoned white sauce containing pieces of sausage. Jus is another close relative: it is usually a thin, concentrated meat sauce made by reducing stock and roasting juices, often without a starch thickener.

The main differences¶

The distinction is therefore functional rather than purely technical. A broth can become gravy if it is reduced and thickened for service; gravy can resemble broth if it is deliberately left thin. The ingredients alone do not settle the matter.

How broth becomes gravy¶

A plain broth requires concentration before it can stand in for a conventional gravy. For roughly 500 ml of finished sauce, a practical method is to reduce 700 ml of unsalted broth to about 500 ml, then thicken it with a roux made from 25 g fat and 25 g plain flour. Whisk the hot liquid in gradually and simmer for 5–8 minutes, until the flour is cooked and the sauce coats a spoon.

A simpler method is to mix 2 teaspoons of cornflour with 2 tablespoons of cold water, stir the slurry into 500 ml of simmering broth, and cook for 1–2 minutes. The result will be smooth and glossy, but less rounded than a flour-based gravy. Season only after reduction, since salt becomes more concentrated as water evaporates.

Broth, stock and gravy in cooking¶

Broth is useful when a dish needs moisture without a heavy sauce: risotto, soups, braises, dumpling dishes and the cooking liquid for grains. It can also replace water in a gravy, where its existing seasoning and extracted flavour shorten the route to a finished sauce.

Stock is generally chosen when body matters. Bones, skin and connective tissue release collagen, which becomes gelatin and gives the cooled liquid a soft set and the hot liquid a fuller mouthfeel. See Gelatin from bones. A gelatin-rich stock can produce a convincing sauce even with little or no flour, although it still needs reduction and careful seasoning.

Gravy is chosen when the liquid must bind a meal together. British roast gravy is commonly spooned over meat, potatoes and vegetables; Gravy for Yorkshire puddings is deliberately generous; Poutine gravy is formulated to penetrate chips and soften curds without becoming watery. These uses demand a sauce with more body than an ordinary broth.

A practical test¶

If the liquid is intended to be sipped from a bowl or used to cook another ingredient, broth is the more precise description. If it is made to be poured over a finished dish and remain on its surface, gravy is more likely. If it does both, the kitchen may choose either word, provided the salt level and thickness suit the job.

The most important practical difference is not the label but the endpoint: broth should taste complete while remaining fluid; gravy should taste concentrated and hold together on the plate. A thin gravy is not necessarily a failed broth, but it is likely to be judged by the standards of sauce rather than soup.
