Foie gras; fwa ɡʁɑ, ˌfwɑːˈɡrɑː) is a specialty food product made of the liver of a duck or goose. According to French law, foie gras is defined as the liver of a duck or goose fattened by gavage (force feeding).
Foie gras is a popular and well-known delicacy in French cuisine. Its flavour is rich, buttery, and delicate, unlike an ordinary duck or goose liver. Foie gras is sold whole or is prepared as mousse, parfait, or pâté, and may also be served as an accompaniment to another food item, such as steak. French law states, "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 there are producers and markets worldwide, particularly in other European nations, the United States, and China.
Gavage-based foie gras production is controversial, due mainly to animal welfare concerns about force-feeding, intensive housing and husbandry, and enlarging the liver to 10 times its usual volume. A number of countries and jurisdictions have laws against force-feeding and the production, import, or sale of foie gras.
As early as 2500 BC, the ancient Egyptians learned that many birds could be fattened through forced overfeeding and began this practice. Whether they particularly sought the fattened livers of birds as a delicacy remains undetermined. In the necropolis of Saqqara, in the tomb of Mereruka, an important royal official, there is a bas relief scene wherein workers grasp geese around the necks to push food down their throats. At the side, stand tables piled with more food pellets and a flask for moistening the feed before giving it to the geese.
The practice of goose fattening spread from Egypt to the Mediterranean. The earliest reference to fattened geese is from the 5th-century-BC Greek poet Cratinus, who wrote of geese-fatteners, yet Egypt maintained its reputation as the source for fattened geese.
