A medicinal tonic soup from Liancheng County in Longyan Prefecture, Fujian, made from the rare White Muscovy duck—a heritage breed with snow-white plumage and jet-black beak and feet recognized as China's sole medicinal duck breed. Only salt is added; no aromatics, no soy sauce. The broth cooks out clear and faintly golden, with an intensity of natural umami from the breed's exceptional glutamic acid content that no ordinary duck can match. A Qing dynasty imperial tribute, it remains prescribed in Fujian traditional medicine for heat-clearing and yin-nourishing.
Liancheng County, Longyan Prefecture, Fujian Province. Local records describe the White Muscovy duck as having been bred in the Liancheng basin for over 700 years. It was formally designated an imperial tribute during the Qing dynasty, and traditional Chinese medicine texts record its efficacy in treating hemoptysis, consumptive disease, unexplained fevers in children, hepatitis, and dysentery. In 2013, the breed received national Geographical Indication Product (protected designation) status; it was included in China's National Livestock and Poultry Genetic Resources Catalogue in 2021 and is officially classified as the country's sole medicinal duck breed.
The broth is nearly clear yet deeply savoury—almost meaty from natural amino acids alone, with no seasoning beyond salt. The duck meat is leaner and less gamey than commercial Pekin duck, with a firm, clean texture and a long finish that justifies the old Chinese phrase 'medicine and food share the same source'.
White Muscovy duck flesh contains 18 amino acids, with glutamic acid alone accounting for 28.71% of the total amino acid profile—approximately twice the proportion found in commercial Pekin duck—producing intense natural umami without any added MSG. Iron and zinc content are 1.5 times higher than ordinary duck, while cholesterol is notably low due to the breed's lean muscle composition and active highland rearing. During the long simmer at around 90°C, collagen from the carcass progressively hydrolyzes into gelatin, creating a silky, mouth-coating quality in what appears to the eye as a clear broth. Extended rearing periods are known to increase the medicinal efficacy of the broth, consistent with higher muscle-fibre density and amino acid accumulation in older birds.
Variations
Rice wine version (黄酒白鹜鸭汤): a splash of Hakka yellow rice wine is added in the final 10 minutes, softening the broth with a gentle grain sweetness and deepening the tonic quality. Ginger and wolfberry version: sliced old ginger and dried goji berries are added from the start for warming, slightly sweet notes—common in postpartum care. Salt-baked white duck: in Liancheng festival cookery, the same breed is prepared as a salt-baked whole duck with bamboo leaf wrapping rather than as a soup.

Ingredients
Serves 4How it's made
7 steps · 20 min
- 130 min
Joint the White Muscovy duck into large pieces; submerge in cold water and soak for 30 minutes to draw out blood.
- 23 min
Place the duck pieces in a pot of cold water; bring to a boil over high heat and blanch for 3 minutes to remove impurities; rinse each piece thoroughly under cold running water.
Watch outBlanch and skim, then rinse every piece clean under cold water — this is what keeps the long simmer producing a clear, faint-gold broth, not a muddy one.
- 32 min
Transfer the cleaned duck pieces to a clay pot or heavy saucepan; add cold water to cover by at least 5 cm and add old ginger slices.
- 45 min
Bring to a full boil over high heat, skimming any remaining foam from the surface until the broth runs clear; reduce immediately to the lowest possible simmer.
Watch outOnce it boils, skim until the surface runs clear, then drop straight to the lowest simmer — a continued hard boil clouds the broth and toughens the duck.
- 5105 min
Simmer covered for 90-120 minutes until the duck is completely tender and the broth has turned a faint, clear gold.
Watch outSimmer low 90–120 minutes until the duck is fully tender and the broth turns faint clear gold — the silkiness comes only from that slow collagen melt.
- 610 min
In the final 10 minutes, add salt to taste only—no other seasoning; remove and discard the ginger slices.
- 72 min
Ladle the clear broth and duck pieces into individual bowls and serve immediately as a tonic dish.
