北京ダック
With the relocation of the Chinese capital to Beijing, supply barge traffic increased in that area. Often these barges spilled water into side-canals, providing a habitat for the ducks. By the time of adoption of five-spice powder, a new breed of duck had been domesticated by Chinese farmers. Nowadays, Peking duck is prepared from the American Pekin duck ("Anas platyrhynchos domestica").
