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.
French fries
The town of Florenceville-Bristol, New Brunswick, headquarters of McCain Foods, calls itself "the French fry capital of the world" and also hosts a museum about potatoes called "Potato World". It is also one of the world's largest manufacturers of frozen French fries and other potato specialties.
