A dish that originated around Suzhou-Wuxi (southern Jiangsu) about a century ago and rose to fame in Shanghai, traditionally made with tiny live river shrimp from Tai Lake or the Huangpu River — the shrimp had to be small enough that a deep-fry could crisp the entire shell to edibility. Codified at restaurants like Lao Zheng Xing in the late 1800s, when the Shanghai concession era was making river-shrimp banquets a marker of city wealth.
Late-Qing Shanghai dish, Tai Lake river shrimp small enough to deep-fry shell-on. Two passes of 200°C+ oil — first locks the shell, second fixes the crunch. Sit longer than 30 seconds and the shells go limp.
Small river shrimp, shells and all, in a glossy translucent sauce with no visible aromatics — Shanghai-style means clean, sweet-savory, almost no chili. The shells go shatteringly crisp from a flash deep-fry; the meat inside stays just-set, sweet, springy. Eat with fingers, suck the head. If the shells are soft, the oil wasn't hot enough — the dish lives at 200°C+.
Two stages of oil, both hot. First fry at 200°C for 10-15 seconds locks the shell crisp without overcooking the meat; cook lifts the shrimp out, raises the oil another 20°C, drops them back for 3-5 seconds to fix the crunch. Then the wok is wiped, sauce (sugar, soy, Shaoxing wine, vinegar) is reduced to a glaze, shrimp tossed back, served immediately. Sit longer than 30 seconds and the glaze pulls moisture into the shells — they go limp.
Variations
Lao Zheng Xing's late-1800s Shanghai version stays sweet-soy-clean; Wuxi cooks lean sweeter; Hangzhou home cooks add a splash of Shaoxing at the glaze step.

Ingredients
How it's made
5 steps · 30 min
- 12 min
Clean river shrimp, removing veins but keeping shells on for texture.
- 222 min
Marinate shrimp briefly in Shaoxing wine and soy sauce for depth of flavor.
- 32 min
Heat sesame oil in a wok until shimmering, then add ginger and scallions to release their aroma.
Watch outGet the oil hot enough to shimmer and just wisp smoke before the shrimp go in — cool oil and the shells go soft and greasy instead of crisping.
- 43 min
Quickly stir-fry shrimp in the aromatic oil until just cooked through.
Watch outPull the shrimp the second the shells flush red and crisp — they cook in a blink, and lingering meat turns dry and mealy.
- 51 min
Add sugar and vinegar, tossing to coat shrimp evenly and enhance their natural sweetness.
Watch outToss in the reduced glaze and plate at once — sit more than half a minute and the sauce draws moisture back into the shells and they go limp.
