Created around 1907 in Harbin by chef Zheng Xingwen (郑兴文) at the Daotai Mansion (道台府), then a Qing-dynasty diplomatic post. Zheng adapted a savory Beijing-style dish, jiao-liu pork (焦熘肉片), for Russian and other foreign guests, who found the original too salty — he reworked it into a sweet-sour dish, originally finished with a hawthorn sweet sauce (山楂甜汁). The dish stayed in Dongbei and now defines the region.
Created circa 1907 in Harbin by Zheng Xingwen at the Daotai Mansion (道台府), adapting Shandong 焦炒肉片 for Russian guests who found the soy too salty — he swapped to a clear sugar-vinegar glaze. Double-fry: 160°C through-cook, 5-min rest, 190°C blister; glaze tossed off-heat under 10 seconds.
Pork loin sliced thin, battered, fried twice until shatter-crisp, then tossed in a clear sweet-sour glaze that stays on the surface — no soak-through. Garnish is matchsticks of carrot, ginger, scallion, and cilantro. The pork should still snap a week later if you took it home; the moment the crust softens, the dish is dead.
Double-frying is the entire technique. First fry at 160°C cooks the pork through and sets the batter; the slices rest 5 minutes (steam escapes); second fry at 190°C blisters the crust into the glassy shell. The glaze must be added off-heat and tossed for under 10 seconds — any longer and the sugar pulls moisture out of the crust, collapsing it. Most failures are over-tossing in too-hot sauce.
Variations
Harbin original keeps the orange-glaze on translucent crust; Liaoning version often adds tomato paste for a redder, thicker sauce (a deviation purists mock); Beijing-Dongbei chains sometimes batter it with cornstarch alone, losing the shatter.

This is all about the double fry and a lightning glaze — fry once at a lower heat to cook through, rest, fry again hot to blister the shell, then toss in the sweet-sour sauce off the heat for under ten seconds so the crust stays glassy instead of going soft.
Ingredients
How it's made
4 steps · 20 min active + 15 min waiting
- 15 min
Slice the pork thinly and marinate it in a mixture of egg and cornstarch for 15 minutes. This creates a light, crisp coating when fried.
Watch outThe batter should be thick enough to cling in a heavy coat, not drip off — that heavy paste is what fries into the crunchy shell.
- 29 min
Heat oil in a wok to 350°F. Fry the pork slices in batches until golden and crisp, about 3 minutes per batch. Drain on paper towels.
Watch outFirst fry to just-golden and firm, not deep-brown; you want it set and cooked through so the second fry can crisp it without scorching.
- 34 min
In a clean pan, combine vinegar, sugar, and a splash of water. Heat until the sugar dissolves and the sauce thickens slightly, about 4 minutes.
Watch outStir occasionally to prevent the sugar from sticking to the bottom of the pan.
- 42 min
Return the pork to the pan, tossing quickly to coat in the sauce. Add julienned carrots and sliced scallions, stirring for 1 minute until just tender. Garnish with cilantro before serving.
Watch outOff the heat, toss just long enough to coat every piece glossy, then plate at once — linger and the crust drinks the sauce and softens.
