Foie gras (French for "fat
liver") is a food product made of the liver of a duck or goose that has been
specially fattened. This fattening is typically achieved through gavage
(force-feeding) corn, according to French law, though outside of France it is
occasionally produced using natural feeding.
The feed, usually corn boiled with fat (to facilitate
ingestion), deposits large amounts of fat in the liver, thereby producing the
buttery consistency sought by the gastronome.
Foie gras is a popular and well-known delicacy in French cuisine. Its flavour is
described as rich, buttery, and delicate, unlike that of a regular duck or goose
liver. Foie gras is sold whole, or is prepared into mousse, parfait, or pâté
(the lowest quality), and may also be served as an accompaniment to another food
item, such as steak. French law states that "Foie gras belongs to the protected
cultural and gastronomical heritage of France."
The technique of gavage dates as far back as 2500 BC, when the ancient Egyptians
began keeping birds for food and deliberately fattened the birds through
force-feeding. Today, France is by far the largest producer and consumer of
foie gras, though it is produced and consumed worldwide, particularly in other
European nations, the United States, and China.
Gavage-based foie gras production is controversial, due to the force feeding
procedure and the possible health consequences of an enlarged liver that could
be faced by the duck or goose. A number of countries and other jurisdictions
have laws against force feeding or the sale of foie gras.
Fully cooked preparations of foie gras
are generally sold in either glass
containers or metal cans for long-term preservation. Whole, fresh foie gras is
usually unavailable in France outside the Christmas period, except in some
producers' markets in the producing regions. Frozen whole foie gras sometimes is
sold in French supermarkets.
Generally, French preparations of foie gras are over low
heat, as fat melts faster from the traditional goose foie gras than the duck
foie gras produced in most other parts of the world. American and other New
World preparations, typically employing duck foie gras, have more recipes and
dish preparations for serving foie gras hot, rather than cool or cold.
Traditional low-heat cooking methods result in terrines,
pâtés, parfaits, foams and mousses of foie gras, often flavored with truffle,
mushrooms or brandy such as cognac or armagnac. These slow-cooked forms of foie
gras are cooled and served at or below room temperature.
Many presentations of foie gras match it to a sweet fruit, including quince,
pears, apples, prunes, plums, cherries, raspberries, blackcurrants,
huckleberries, figs or elderberries. These can be in the form of sauces, coulis,
jam, stewed, caramelized or pureed.

Sauces include onion or leek-based sauces, red wine or
fortified red wine reductions, truffle and mushroom sauces or wasabi drizzles.
It is commonly served accompanied with crusty or toasted bread such as a
brioche, or, more rustically, toasted baguette ends.
If wine is drunk with foie gras, it is generally white wine,
often very sweet, such as Sauternes or Monbazillac.
Foie gras is a luxury dish. In France, it is mainly consumed
on special occasions, such as Christmas or New Year's Eve réveillon dinners,
though the recent increased availability of foie gras has made it a less
Duck foie gras is the slightly cheaper and, since a change of production
methods in the 1950s, by far the most common kind, particularly in the US. The
taste of duck foie gras is often referred to as musky with a subtle bitterness.
Goose foie gras is noted for being less gamey and smoother, with a more delicate
