Rows of golden tofu squares gleam in orange-red braising sauce, each crowned by a plump shrimp—the 'gold-inlaid white jade box' of the original name made literal. The deep-fried shell gives way to silky tofu and a juicy pork-shrimp core; a lightly sweet-sour, lacquered sauce rounds out a dish that is equal parts homestyle comfort and Wuxi banquet showpiece.
Chef Liu Junying (1901–1991) of Wuxi's Yingbin Lou restaurant (est. 1930) created this dish in the 1940s by elevating a common home-style stuffed fried tofu: he substituted Wuxi's specialty 'small-box tofu' for ordinary fried tofu and added shrimp to the pork filling, naming the result 'Gold-Inlaid White Jade Box' (金镶白玉箱)—pork as gold, shrimp as jade. During the Cultural Revolution's 'destroy the four olds' campaign, the character for gold was politically banned; the name was changed to the near-homophone 镜箱 (mirror box), referencing the block's resemblance to a traditional women's cosmetic case. Liu Junying is regarded as one of the founding masters of modern Wuxi (锡) cuisine.
Snappy shrimp, silky tofu, savory pork filling—three textures in a single bite, unified by sweet-savory lacquered sauce with a flicker of tomato tartness that keeps you reaching for the next piece.
Deep-frying at 180 °C rapidly denatures the outer protein layer of the tofu, forming a firm golden shell; internal moisture vaporizes to create a sponge-like structure that accepts the hollowed filling while staying tender inside. In the braising sauce, tomato paste supplies free glutamate while soy sauce contributes inosinate and guanylate—triggering umami synergy that amplifies savory intensity well beyond any single ingredient. Cornstarch gelatinizes above 80 °C to create the glossy, lacquer-like glaze that clings to the tofu skin and seals in flavor.
Variations
Wuxi's own 'small-box tofu'—finer-grained than standard firm tofu—gives the best result, but any non-silken firm tofu works. A vegetarian adaptation replaces pork and shrimp with minced winter bamboo shoots and water chestnuts; vegetable broth replaces pork stock. Some versions add a splash of Shaoxing wine mid-braise for aromatic depth.

How it's made
7 steps · 45 min active + 15 min waiting
- 15 min
Drain and press tofu firmly to remove excess moisture; cut into 4 × 3 × 3 cm rectangular blocks.
- 28 min
Deep-fry tofu blocks in oil at 180 °C for 4–5 minutes until the exterior forms a firm golden crust; drain on paper and cool slightly.
Watch outDeep-fry at 180°C until a firm golden crust forms — that shell is what puffs the inside into a sponge to hollow out; a soft crust tears when you scoop the cavity.
- 310 min
Using the handle of a small spoon, hollow out the center of each fried tofu block—leaving a 5 mm base and intact sides—to create a snug cavity for filling.
- 410 min
Season ground pork with soy sauce, Shaoxing rice wine, minced ginger, salt, and a little cornstarch; stir until sticky. Pack each cavity with pork filling, then press one large shrimp horizontally across the top.
- 55 min
Arrange filled tofu shrimp-side down in a single layer in a wok; add Shaoxing rice wine, soy sauce, rock sugar, tomato paste, and pork broth; bring to a boil.
- 66 min
Cover and braise over low heat for 6 minutes until the filling is cooked through and the tofu has absorbed the braising liquid.
- 75 min
Remove the lid, raise heat to reduce the sauce until glossy and coating; add cornstarch slurry, drizzle sesame oil around the edge, and flip the pieces shrimp-side up onto a serving plate; spoon sauce over and serve.
Watch outReduce the sauce until it turns glossy and coats the tofu before the slurry — watery sauce won't cling, and the shine is the sign it's ready.
