A single intact premium back fin, braised to translucent tenderness through repeated infusions of rich stock, then presented in an open-fan arrangement with a glossy amber sauce. Tianjin's undisputed centrepiece banquet dish, celebrated as the 'king of grand dishes'—the term 通天 denoting an unbroken fin from dorsal base to tip.
Braised Whole Shark Fin was created by Wang Enrong (王恩荣), recognized in early-twentieth-century Tianjin restaurant circles as the 'shark fin king' (鱼翅大王). The term 通天 refers to the use of a single fin extending unbroken from dorsal base to tip, as opposed to re-assembled scattered fin needles—a distinction that both elevated ingredient cost and demonstrated mastery of the extended preparation technique. In 1955 the dish was formally listed among the twelve official signature dishes of Tianjin cuisine. In 1987, chef Kou Zhongyi of the Tianjin Roast Duck Restaurant refined the preparation process and won the Group Star Cup at a Tianjin culinary competition, cementing its status as the premier banquet showpiece of the Tianjin canon.
The fin arrives glistening at the table in its full open-fan shape. Each mouthful of softened fin needles carries a gelatinous, almost weightless resistance—sustained umami from the braising stock clings to every fibre, with a savouriness that lingers long after the fin dissolves on the palate.
Shark fin is composed almost entirely of collagen fibres (the fin needles). Extended soaking removes impurities; multiple cycles of gentle simmering in stock gradually hydrolyse the outer collagen sheaths into gelatin, which lubricates the needles and thickens the surrounding liquid naturally. The final 扒 technique—braising in a rich reduced stock finished with a thin starch slurry—ensures the sauce coats every needle in a translucent amber glaze. The 大翻勺 (single decisive wok flip) presents the intact fin golden-side up without fracturing the fan arrangement, a manoeuvre that can only be executed once and requires years of wok-skill practice.
Variations
Tianjin purists explicitly reject any version that re-assembles scattered fin needles in a fan mould—the 通天 name mandates a single intact fin. A common banquet pairing presents the whole fin alongside braised abalone in a shared sauce. Outside the flagship tradition, some restaurants substitute high-quality imitation fin (konjac-based) to sidestep contemporary conservation concerns while preserving the dish's visual drama and textural concept.

Ingredients

How it's made
7 steps · 12 hours
- 1720 min
Soak one whole dried back shark fin in cold water for 12 hours, changing water every 4 hours to remove impurities; drain.
- 2120 min
Place the fin in a pot, cover with cold water, bring to a boil, then reduce heat and simmer 2 hours; drain, discard the water, and gently scrape away any remaining dark skin; rinse clean.
Watch outSimmer, then gently scrape away the dark skin — leave it on and the fin tastes muddy; the surface should come clean and pale.
- 390 min
Transfer the cleaned fin to a clay pot; cover with rich chicken-pork stock, add 2 ginger slices and 1 scallion stalk; simmer on low heat 90 minutes to infuse flavour deep into the fin.
- 445 min
Discard the stock and replace with fresh seasoned stock (add soy sauce, Shaoxing wine, and oyster sauce); simmer a further 45 minutes until the fin is fully tender and translucent throughout.
Watch outBraise long in fresh seasoned stock until the needles turn tender and translucent throughout — fin has no flavor of its own, so it has to drink the stock in.
- 55 min
In a wide flat-bottomed wok, heat a ladleful of the braising stock; add oyster sauce and a touch of dark soy; lay the drained fin flat, golden-side down, and braise over medium heat for 5 minutes.
- 63 min
Mix 15g cornstarch with 30ml cold water; stream into the wok while gently tilting to distribute the thickening sauce; cook 2–3 minutes until the sauce becomes clear and glazes the fin.
- 72 min
Execute the 大翻勺—grip the wok handle firmly and arc the wok away from you in one decisive motion to invert the fin golden-side up; slide carefully onto a serving platter and spoon over remaining sauce.
