The dish is prized for the thin, crispy skin, with authentic versions of the dish serving mostly the skin and little meat, sliced in front of the diners by the cook. Ducks bred specially for the dish are slaughtered after 65 days and seasoned before being roasted in a closed or hung oven. The meat is often eaten with pancakes, spring onions, and hoisin sauce or sweet bean sauce. The two most notable restaurants in Beijing which serve this delicacy are Quanjude and Bianyifang, two centuries-old establishments which have become household names. A variant of the dish known as crispy aromatic duck has been created by the Chinese community in the United Kingdom.
