A braised duck from Chongzuo in southwestern Guangxi, where duck pieces slow-cook with ripe wampee fruit. The fruit's citric and malic acids tenderize the meat while aromatic compounds in the skin perfume the braising liquid, which reduces to a glossy amber sweet-sour glaze.
Chongzuo sits in the southwestern tip of Guangxi along the Vietnamese border and is home to one of China's largest Zhuang communities. Wampee fruit ripens in early summer, and local Zhuang cooks learned to pair surplus fruit with barnyard duck, letting its tartness cut the bird's rich fat and its aromatic skin compounds perfume the braise. The 2025 Guangxi Intangible Cultural Heritage Food Map, published by the Guangxi Department of Culture and Tourism, lists this dish as one of Chongzuo's two signature heritage dishes, alongside Yellow Ginger Chicken Soup.
Yielding duck meat that falls from the bone, bathed in amber sauce that is simultaneously sour, sweet, and faintly floral-bitter; the dissolved wampee skin enriches the glaze.
Wampee fruit's dominant organic acids—citric and malic—lower the braising liquid's pH, partially denaturing muscle proteins and accelerating hydrolysis of collagen into gelatin so connective tissue around the bones softens and the sauce thickens naturally. Coumarin compounds and volatile alkaloids in the fruit skin, including wampee cinnamoyl amides, release during prolonged heat and bind in the reduced sauce, contributing the characteristic floral-bitter fragrance.
Variations
Some cooks use unripe green wampee for a sharper sourness that more aggressively strips the duck's gaminess. Adding fermented sour bamboo shoot (酸笋) alongside the fruit deepens the acidity. A Zhuang festival version adds glutinous rice wine to the braising liquid, sweetening the finish and enriching the sauce color.

Ingredients

How it's made
8 steps · 30 min
- 13 min
Chop duck into 6-cm pieces; blanch in a pot of boiling water for 3 minutes to remove blood and excess fat, then drain and rinse under cold water.
- 25 min
Wash wampee fruit; halve and remove seeds, squeezing the juice into a bowl. Reserve the fruit skins.
- 32 min
Heat 2 tablespoons of oil in a wok over medium-high heat; add ginger slices, lightly crushed garlic cloves, and dried chilies and stir-fry until fragrant, about 2 minutes.
- 46 min
Add the drained duck pieces and stir-fry until the skin begins to color and renders some fat, about 6 minutes.
Watch outFry the duck until the skin turns from pale to golden and a slick of clear duck fat pools in the wok — that rendered fat is your cue the skin has set and won't stew grey.
- 53 min
Pour in the wampee juice and reserved skins, dark soy sauce, light soy sauce, and Shaoxing wine; toss to coat the duck pieces evenly.
- 645 min
Add enough hot water to half-submerge the duck, bring to a boil, then reduce heat to the lowest setting, cover, and braise for 45 minutes.
- 710 min
Remove the lid, raise heat to high, and reduce the sauce while gently stirring until it thickens and glossily coats the duck, about 10 minutes.
Watch outReduce over high heat, stirring gently, until the sauce goes thick and glossy and coats the duck like a glaze — pull it there before it dries past and the wampee bitterness sharpens.

Taste and adjust seasoning with salt; scatter sliced scallions over the top and transfer to a platter.
