Three-Nested Duck

Three-Nested Duck is a traditional dish of Yangzhou and neighbouring Gaoyou in Jiangsu, built on the Qing-dynasty Yangzhou tradition of whole-deboning poultry. The recipe collection Tiao Ding Ji, compiled by the Yangzhou salt merchant Tong Yuejian during the Qianlong reign in the 18th century, records an earlier two-bird "nested duck": a boned domestic duck stuffed with a boned pressed duck and steamed until very tender. Yangzhou restaurant cooks later extended this by deboning a wild duck inside the home duck and a squab inside the wild duck, creating the three-bird version; the exact cook and date of that step are not reliably documented.

Cutting through the dish reveals three concentric layers: an outer wrap of fatty, tender home duck, a middle layer of leaner, more savoury wild duck, and a delicate squab at the core, all bathed in a clear yet deeply rich broth that lingers on the palate.

The technique rests on whole-deboning: each bird is opened at the neck and back and its entire skeleton drawn out while the skin and overall shape stay intact, so the three can be nested smallest-to-largest into one seemingly whole duck. After a brief blanch to set the skin and remove blood, the nested birds are stewed gently in a water-bath clay pot in ample stock kept just below a rolling boil; this slow, low heat melts the abundant skin-and-connective-tissue collagen into gelatin that gives the broth its body, while never agitating the liquid enough to emulsify the fat and turn it cloudy. Diligent skimming of surface scum keeps the soup clear, and the fat rendered from the outer home duck bastes the leaner wild duck and squab within, carrying flavour inward across the long cook.
