Foie gras is a luxury food product made of the liver of a duck or goose that has been specially fattened. By French law, foie gras is defined as the liver of a duck or goose fattened by force-feeding corn with a feeding tube, a process also known as gavage.
Foie gras is a popular and well-known delicacy in French cuisine. Its flavor is described as rich, buttery, and delicate, unlike that of an ordinary duck or goose liver. French law states that "Foie gras belongs to the protected cultural and gastronomical heritage of France."[5]
