Duck Foie Gras- A  food product made of the liver of a duck or goose that has been specially fattened. 

This gourmet product is a popular and well-known delicacy in French cuisine. Its flavor 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.

France is the leading producer and consumer of duck and goose foie gras.
