The dish is associated with Zeng Guofan's tenure as Zhili Governor from 1868 to 1870, when the official kitchens drew on the freshwater fish of nearby Baiyangdian Lake — one of North China's most celebrated fishing grounds. The name 'bèng' (蹦, to leap or jump) likely describes the Zhili high-heat cooking technique in which fish is deep-fried until the skin crisps and the flesh contracts tautly, then doused with sauce in a burst of sizzling steam. Because documentary sources on this specific dish are sparse, the precise account of its naming is rendered here as tradition holds it.
The crisp golden skin shatters on first contact; beneath it, moist white flesh flakes cleanly. Soy-ginger sauce clings in a glossy coat, savory and faintly sweet, with a back note of vinegar that brightens the whole mouth.
Zeng's Braised Fish achieves its textural contrast through a two-stage process. The initial deep-fry at 180–200 °C drives off surface moisture, triggering Maillard browning on the skin — hundreds of new aromatic compounds form in the first minute of contact. The crisp shell also acts as a structural barrier, keeping the interior moist. When the hot fried fish meets the sauce, the steep temperature gradient causes rapid steam release and flash caramelization of the sauce sugars around the fish, helping the glaze penetrate the outer layer without softening the crust entirely.
Variations
The dish is sometimes made with whole mandarin fish (鳜鱼) for a prestige banquet version. A sweeter Shandong-influenced variation adds more rock sugar and a splash of Zhenjiang vinegar for a sweet-sour glaze. Home cooks often reduce the oil and pan-fry rather than deep-fry, yielding a less crisp but equally flavorful result.

How it's made

- 115 min
Clean the fish thoroughly; score both sides with diagonal cuts at 2 cm intervals to help heat penetrate. Rub inside and out with salt, white pepper, and Shaoxing wine. Marinate for 15 minutes; pat surface dry before frying.
- 28 min
Heat 4 tbsp vegetable oil in a wok over high heat until it reaches 180–200 °C. Gently lower the fish in and fry undisturbed for 3–4 minutes per side until the skin is golden and crisp. Remove carefully and drain.
Watch outGet the oil to a proper shimmering high heat before the fish goes in and leave it undisturbed — a hot enough pan crisps the skin golden and keeps the flesh from sticking and tearing when you turn it.
- 33 min
Discard most of the oil, leaving about 1 tbsp. Add scallion sections and ginger slices and fry over medium-high heat until fragrant and lightly charred, about 1 minute.
- 43 min
Add garlic and stir briefly. Add soy sauce, dark soy sauce for color, Shaoxing wine, sugar, and enough water to come 1 cm up the side of the fish. Bring to a boil.
- 58 min
Gently lower the fried fish back into the wok. Braise over medium heat for 6–8 minutes, spooning sauce over the top repeatedly to glaze.
Watch outBraise on medium and keep spooning sauce over the top — repeated basting glazes and flavours the fish evenly without having to flip and risk breaking it.
- 63 min
Add a splash of rice vinegar; increase heat to high to reduce the sauce until it thickens to a glossy glaze, about 2 minutes.
Watch outAdd the vinegar, then jack the heat to reduce until the sauce turns thick and glossy — swirl the pan so it doesn't catch, and pull it the moment it coats a spoon.

Transfer the fish to a serving plate; pour any remaining sauce over it. Garnish with scallion greens and serve immediately.
