Foie gras
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.
Foie gras controversy
The production of foie gras (the liver of a duck or a goose that has been specially fattened) involves the controversial force-feeding of birds with more food than they would eat in the wild, and more than they would voluntarily eat domestically. The feed, usually corn boiled with fat (to facilitate ingestion), deposits large amounts of fat in the liver, thereby producing the fatty consistency sought by some gastronomes.
