A golden West Lake thick soup of steamed, shredded mandarin fish in a chicken-stock base with ham, bamboo shoot, and mushroom, thickened and finished with egg yolk and a touch of vinegar — so close to crab in color and taste it is nicknamed 'mock-crab soup.'
A traditional Hangzhou dish of the West Lake. Its exact origin cannot be firmly established, but it is one of the city's most famous and long-recorded dishes, tied by tradition to a Bianjing-born fishmonger-cook known as Song Wusao ('Fifth Sister Song'), who fled south to the Southern Song capital Lin'an (Hangzhou) and sold fish soup by the lake. Zhou Mi's Wulin Jiushi records that in 1179 the retired emperor Gaozong (Zhao Gou), boating on West Lake, summoned her aboard and rewarded her on learning she too came from the old capital; Wu Zimu's Mengliang Lu lists 'Song Wusao's fish soup outside Qiantang Gate' among Lin'an's famous shops. The dish has been made in Hangzhou for some eight centuries.
A thick, glossy, amber-gold soup you eat by the spoonful. The fish comes apart in soft, silky flakes that genuinely read as crabmeat; under it the chicken stock is deeply savory, the ham and bamboo shoot add a salty bite and a clean crunch, and a late hit of vinegar and fresh ginger cuts the richness and lifts the whole bowl.
Steaming, not poaching, sets the fish: it keeps the flesh moist and intact so it can be pulled into clean shreds rather than disintegrating in the broth. The crab-like savor is real umami synergy — glutamate from the ham, mushroom, and bamboo shoot multiplies with the inosinate of the fish and chicken stock, so the combined savoriness far exceeds any one ingredient. Wet-starch slurry gelatinizes to give the soup its clinging, spoon-coating body; the egg yolk, streamed in off a strong simmer and stirred at once, sets into fine threads and turns the soup gold. Vinegar goes in last, after the boil, so its aroma is not driven off.
Variations
Perch is the common stand-in when mandarin fish is unavailable, and the dish is often called 'mock-crab soup' for its crab-like result. Some cooks use only the egg yolk for a cleaner gold, others add the whole egg; the ginger and vinegar at the finish are essential to the Hangzhou style. A close relative on the West Lake table is 'braised fish-head soup' (chai-hui yu-tou), likewise associated with the Song Wusao tradition.

How it's made
8 steps · 20 min
- 115 min
Scale, gut and clean a whole mandarin fish (or perch); rub lightly with salt, add ginger and Shaoxing wine, and let it marinate about 15 minutes.
- 210 min
Steam the fish over high heat about 10 minutes until just cooked through, then lift out and let it cool enough to handle.
Watch outSteam just until the flesh turns opaque and flakes off the bone, about ten minutes — overcook it and it goes dry and won't pull into clean shreds.
- 38 min
Remove all skin and bones and pull the flesh into fine shreds, reserving any steaming juices.
- 43 min
Heat lard in a wok, fry the scallion until fragrant, pour in the chicken stock and bring to a boil, then splash in the Shaoxing wine.
- 53 min
Add the shredded bamboo shoot and mushroom; once boiling again, add the fish shreds with their juices, then season with soy sauce, salt and pepper.
- 61 min
When it returns to a boil, stir in the wet-starch slurry to thicken to a clinging consistency.
Watch outAdd the starch slurry only once it's at a full boil and stream it in slowly while stirring, so the soup thickens to a smooth coat that clings to the spoon, not a gluey clump.
- 72 min
Stream the beaten egg yolk into the soup and stir at once into fine threads; when it boils again add the vinegar and a spoon of hot lard.
Watch outDrizzle the beaten yolk in a thin thread over a strong simmer and stir at once so it sets into fine golden strands; add the vinegar only after it returns to a boil or the sourness cooks off flat.
- 81 min
Ladle into a bowl and finish with ham shreds and shredded ginger.
