Hunan's most beloved pantry pairing: smoke-cured pork belly sliced thin and stir-fried with 腊八豆—Changsha's fermented soybeans brined with chili, ginger, and rice wine until savory-funky and deeply umami. Two preserved ingredients, one irreplaceable dish.
Fermented soybeans (腊八豆) have anchored Changsha kitchens since at least the Qing Kangxi era, when the practice of home-fermenting soybeans after the Laba Festival—the eighth day of the twelfth lunar month—was documented across Hunan as a winter staple. The name derives from the Buddhist holiday on which temples cooked offerings for the faithful, and local households adopted the date as the signal to begin their own batch. Cured pork belly smoked over pine and rice straw predates the dish as a shared Han Chinese winter preservation tradition. The pairing of both preserved ingredients solidified into a Changsha household signature not through court or restaurant invention but through daily repetition across generations, and it remains the province's most widely cooked weekly dish.
Salty, smoky, and profoundly savory—rendered cured pork fat mingles with fermented soybean umami, chili heat punctuating every bite.
Curing and pine-smoke concentrate glutamates in pork through protein denaturation and Maillard reactions; phenolic compounds from wood smoke (guaiacol, syringol) create the characteristic smoky aroma. 腊八豆 fermentation by Bacillus species and mold hydrolyzes soy protein into free amino acids—glutamate content rises sharply—and generates aminobutyric acids and bioavailable isoflavones. The high-heat wok evaporates surface water rapidly, triggering secondary Maillard browning on both ingredients, producing pyrazines and furans that deepen complexity. Capsaicin from dried chili stimulates nociceptors without masking the underlying umami. The entire stir-fry window is under five minutes: sustained heat would leach the soybeans' textural integrity.
Variations
The classic steamed version layers soybeans over sliced cured pork and steams for thirty minutes—softer and more fragrant. Lakeside variants substitute cured fish (腊鱼) for pork belly. A vegetarian adaptation pairs 腊八豆 with dry-fried tofu skin.

How it's made
7 steps · 30 min
- 125 min
Rinse cured pork belly under warm water, then soak in warm water for 20-25 minutes to reduce excess salt; drain and slice into 3mm thick pieces
Watch outSoak the cured belly 20–25 minutes to pull the excess salt before slicing — skip it and the finished dish comes out punishingly salty.
- 24 min
Rinse fermented soybeans and drain well; cut dried chili into segments, slice ginger, and smash garlic cloves
- 33 min
Heat a dry wok over high heat until just smoking; add pork belly slices in a single layer and dry-fry without stirring until fat renders and edges curl, about 2-3 minutes
Watch outDry-fry the belly without oil until the fat renders and the edges curl — that rendered lard is the fat everything else cooks in.
- 41 min
Push pork to the sides of the wok; drizzle in a small amount of vegetable oil in the center, then add ginger, garlic, and dried chili; stir-fry the aromatics 30 seconds until fragrant
- 53 min
Add the fermented soybeans to the center; stir everything together over medium-high heat for 2-3 minutes until soybeans are lightly caramelized and fragrant
Watch outFry the fermented soybeans until lightly caramelized and fragrant — raw beans taste flat; a little browning wakes up the whole dish.
- 61 min
Drizzle soy sauce and Shaoxing rice wine around the edges of the wok; toss vigorously 30 seconds over high heat
- 71 min
Taste for salt—腊八豆 is already heavily salted, so little or no additional salt is needed; plate immediately and serve with steamed rice
