Zhangpu Force-Fed Stuffed Duck

Legend holds that Cai Xin (1707–1799), a Grand Secretary of the Qing court from Zhangpu, brought Beijing's force-feeding duck technique to his home village of Shiliu upon retirement. According to local oral tradition, his wife taught the method to neighbouring families; the practice spread through the village and became inseparable from Shiliu's fertile duck-farming landscape. A parallel folk account traces the dish to the Wanli reign of the Ming dynasty, when a resourceful woman in Meiling village hand-fed fattening ducks to solve a pre-festival shortage. Whichever story is truer, the result is a duck whose twenty-day hand-feeding regime sets it apart from ordinary poultry.

The meat is fine-grained and sweetly rich with a silky quality from evenly distributed intramuscular fat; the skin is thin and yielding. The prized powder liver dissolves like cultured butter on the tongue — luxuriantly smooth, with a gentle livery depth.

Force-feeding floods the duck's liver with carbohydrates far exceeding metabolic needs; hepatocytes convert the excess into triglycerides that accumulate as fat droplets within cells — the same hepatic lipidosis that produces French foie gras. Liver fat content can reach 50–60% of wet weight, dissolving the granular protein texture and creating the characteristic powder-liver softness. Simultaneous build-up of intramuscular fat in the breast improves water-holding capacity, keeping the meat moist even during long simmering. Duck subcutaneous fat melts at approximately 31°C — lower than pork lard at roughly 40°C — so it dissolves on contact with the tongue, creating the hallmark 'fatty but not greasy' sensation.
