Squirrel-shaped mandarin fish is a Suzhou-style dish: a boned, scored fish is fried so the flesh opens like a squirrel's tail, then covered with sweet-and-sour sauce.

Squirrel-shaped mandarin fish is a Suzhou dish: the fish is boned and scored in a cross-hatch, coated in starch or egg-yolk batter and fried so the flesh opens like a squirrel's tail, then covered with a sweet-and-sour sauce. Songhelou on Suzhou's Guanqian Street is one restaurant often mentioned. A secondhand quotation from the Qing-dynasty Tiaodingji describes a fried fish made in the squirrel style; the quotation gives no year, and the original book was not checked. Songhelou was founded in the Qianlong years, and accounts give two different years, 1737 and 1757.
What
Squirrel-shaped mandarin fish is a Suzhou dish. A mandarin fish is boned with the head and tail kept, the flesh is scored in a diamond pattern, battered and fried until the cuts open like a squirrel's tail, and covered with a hot sweet-and-sour sauce.1,2,6,8
When
The sources listed here hold no dated record of the mandarin-fish dish. A secondhand quotation from the Qing-dynasty Tiaodingji describes coating a fish in egg yolk, frying it golden and shaping it in the squirrel style, a method regarded as a forerunner of the dish; the quotation gives no year, and the original book was not checked. Songhelou opened in the Qianlong years, and accounts give different years.1,2,3,4,5,6
Where
Suzhou, around Guanqian Street, where Songhelou stands on Taijian Lane. Outside Suzhou, other fish such as yellow croaker often stand in for mandarin fish.1,2,3
How
The mandarin fish is boned with the head kept, and the flesh is scored in a diamond pattern, dusted with starch or dipped in egg-yolk batter and fried in hot oil until the cuts open. A sweet-and-sour sauce goes over it, often made with tomato today, with bamboo shoot, shiitake mushrooms, peas or pine nuts.1,6,7,8
Why
Apart from a folk tale, the sources listed here do not explain why the dish is shaped like a squirrel. The name is explained in two ways: by the shape of the fish, or by the sizzling sound when the sauce is poured on.1,6
Impact and influence
Songhelou is a China Time-honored Brand, named in 1999 and confirmed again in 2006, and squirrel-shaped mandarin fish is its signature dish. Songhelou opened a London branch in Chinatown in 2025; a noodle dish topped with squirrel-shaped fish appeared in a March 2025 London restaurant report, as menu information before the opening.3,4,5
Legend has it that when the Qianlong Emperor toured the south he went to Songhelou and asked to eat a mandarin fish from the restaurant's pond, but that fish was kept as an offering to the gods. To avoid offending the gods, the cook shaped the fish like a squirrel, and the emperor was pleased.
Told in: A folk legend told in an encyclopedia entry; Chinese Wikipedia retells a similar tale.
This is a simplified home version, not the traditional restaurant method.
In restaurants squirrel-shaped fish is boned, shaped, fried and sauced with care. This is the simpler way I make it at home: ask the fishmonger to prepare the fish, score it myself, dust it with starch and fry it through, then cook a sweet-sour tomato sauce to pour over. The amounts and timings below are my own choices at home, informed by a few published recipes.
Ingredients
Mandarin fish (or yellow croaker, carp or another white fish) 1 fish, about 1 kg, scaled and gutted by the fishmonger
Salt 1 teaspoon
Ground pepper 1/2 teaspoon
Cooking wine 2 tablespoons
Cornstarch for dusting 80 g
Cooking oil for frying about 1 liter, depending on the pan
Soaked wood ear fungus 20 g, torn into small pieces
Bamboo shoot 40 g, diced
Minced ginger 1 teaspoon
Tomato paste 3 tablespoons
Light soy sauce 1 tablespoon
White vinegar 2 tablespoons
Sugar 1 tablespoon
Water for the sauce 8 tablespoons
Starch slurry 3 teaspoons cornstarch stirred into 6 teaspoons water
Sesame oil a few drops
Pine nuts 1 tablespoon
Steps
Rinse the fish and pat it dry. Cut off the head, slice the flesh off both sides of the backbone while keeping the two fillets joined at the tail, and take out the backbone. The fishmonger can do this step for you.
Lay the fillets skin side down and score them on a slant in a diamond pattern, cutting nearly to the skin but not through it. Split the head in half.
Rub the salt, pepper and wine over the fillets and head and leave them for about 10 minutes, then pat dry. Dust with cornstarch, getting it into the cuts, and shake off the extra.
Heat the oil to about 180 degrees Celsius by thermometer. Start by frying the head, then lower the fish in by the tail and spoon hot oil over any part not under the oil. Fry for about 10 minutes until golden and crisp. The fish must be cooked through, with the thick part white and opaque. Lift it out, drain it and set it on a plate, with head and tail lined up.
In a separate pan, heat 2 tablespoons of oil and fry the wood ear, bamboo shoot and ginger for about 2 minutes. Add the tomato paste, soy sauce, vinegar, sugar and 8 tablespoons of water and bring to a boil.
Add the starch slurry in two additions, stirring each time, and cook until thick and glossy, then add a few drops of sesame oil.
Pour the hot sauce over the fish, scatter the pine nuts on top and serve at once.
Tips
I score the flesh as closely as I can, because the cuts open more easily in the oil that way.
When I cannot find mandarin fish I use yellow croaker or another white fish; the recipes I looked at also use carp and croaker.
