A whole mandarin fish, deboned and scored into a crosshatch, fried until the flesh fans open into golden fronds like a squirrel's tail — then drenched tableside in a hot sweet-and-sour tomato glaze that sizzles. That soft squeak is how the dish got its name, and the story of Emperor Qianlong.
If Suzhou had to be represented by a single dish, it would be squirrel mandarin fish (松鼠鳜鱼, Sōngshǔ guìyú) — a whole freshwater mandarin fish, painstakingly deboned so only the head and tail remain, then scored with deep crosshatch cuts. When it is battered and lowered into hot oil, each scored square curls open into a little frond, and the whole fish blooms into golden fronds that look like pinecone scales or a bushy squirrel's tail, crisp from head to tail.
This is Su cuisine (苏帮菜), one of the pillars of Jiangsu (苏菜) cooking — the refined Jiangnan style of canals and classical gardens. It isn't spicy; it prizes fine knife work and a gentle sweet-and-savory balance. What makes squirrel fish special is timing and technique: the fish has to stay crisp all over, the sweet-and-sour tomato sauce has to be hot enough to sizzle and "squeak" when it lands, and the flesh underneath has to stay soft and juicy rather than dry out.
Squirrel mandarin fish is not street food eaten on the move — it's a sit-down dish, served whole on a long plate, head raised and tail curled as if the fish is mid-leap, lacquered in a glossy red-orange sauce. It's what locals order when they bring out-of-town guests to the table, and it's the first thing a first-time visitor to this city of canals and gardens should try.
The name squirrel fish comes from its shape after frying: the crosshatched flesh fans open into curls that resemble the fur of a squirrel's tail or the scales of a pinecone, and when the hot sauce hits the crisp surface it sizzles with a faint squeak. That little squeak — the sound and the shape together — is what people named the dish for.
Legend has it that Emperor Qianlong (乾隆) of the Qing dynasty, travelling through Suzhou in disguise, dined at Songhelou (松鹤楼), where the chef prepared a deboned fish carved into a squirrel shape and dressed in sweet-and-sour sauce. The emperor was so taken with it that the dish became famous across the country, and on every later journey south to Suzhou he is said to have stopped at the same restaurant to order it again — the story that turned squirrel fish into the dish the whole city is known for.
A single fish passes through the chef's hands in several stages. Here's what happens before it reaches your table.
It starts with freshwater mandarin fish (鳜鱼, guìyú) — a firm, low-bone fish from the rivers and lakes of Jiangnan. It is carefully deboned through the whole body, leaving only the head and tail intact. This is the stage that demands the most skill and the sharpest knife of the entire dish.
The flesh is scored into a deep crosshatch (the pinecone cut) without cutting through the skin. Once fried, each little square curls outward into a crisp frond, like a squirrel's tail. The precision of this knife work is exactly what separates a great kitchen from an ordinary one.
The fish is dredged in batter so it coats the scored grooves, then deep-fried in hot oil until the fronds bloom and the whole fish turns golden and crisp. Some kitchens fry it twice for extra crunch, then stand it on the plate head-up and tail-curled as if it's leaping.
A sweet-and-sour tomato sauce (vinegar, sugar, tomato) is reduced until it's hot and glossy, then poured over the crisp fish tableside. The hiss it makes — a soft squeak — is the sign the frying was timed right. The sauce lands sweet-and-sour, the flesh inside still soft and juicy.
Squirrel fish arrives whole on a long plate, head raised and tail curled, the flesh blooming into golden fronds all along the body. Many restaurants bring the hot sweet-and-sour tomato sauce to the table and pour it over in front of you — the squeak and the wisp of steam rising off the fish are the moment everyone reaches for a camera.
It's a dish for sharing across the table, not a solo plate. One fish comfortably feeds three or four. Lift the crisp fronds together with the sauce pooled beneath and eat them with hot steamed rice — soft and juicy inside, crisp on the surface. The sauce-soaked head is the prize that the serious fish-lovers go for.
Price: at an ordinary Suzhou restaurant, around ¥120–180 a plate (about ฿600–900). At an institution or for a large fish, ¥180–260 (฿900–1,300), depending on the size and type of fish.
Squirrel fish is a dish where the chef's skill decides everything. A good kitchen serves it crisp outside and tender within, with a balanced sweet-and-sour sauce. But some spots in the tourist streets rush it, and the fish can come out soggy and soft instead of crisp, or the sauce cloyingly sweet — and the magic of the dish disappears the moment it does.
The safe bet is a genuine Su-cuisine house known for this dish (Songhelou, Deyuelou, Wumen Renjia) rather than a canal-street stall set up more for photos than flavour. And if you want it at its crispest, dig in right after the sauce is poured — don't let it sit, because the fish slowly soaks up the sauce and softens.
Places Suzhou locals know, all famous for this dish, all verified open.
If you want to eat squirrel fish where it means the most, Songhelou is the answer. This Guanqian Street restaurant has been open since 1737 (it began as a noodle house) and is the place the Qianlong legend is tied to — the house everyone credits as the original. It now runs several branches in Suzhou, with the oldest on Guanqian Street. It gets very busy in high season, so book ahead or visit outside peak meal hours.
Another of Suzhou's legendary restaurants, on Taijian Lane (太监弄) — the city's "eat street" — a short walk from Songhelou. Deyuelou is known for its squirrel fish and for classic Su-cuisine dishes built on produce from Taihu Lake: river shrimp, spring chicken and rice-flour steamed pork among them. Locals and Chinese visitors rate it as highly as the original house, in a traditional Jiangnan dining room.
A restaurant devoted to cooking old Suzhou recipes faithfully, set in the garden courtyard of the (free-to-enter) Suzhou folk-custom museum. The setting is quiet and old-world, like eating in a Jiangnan family home rather than a busy dining hall. Its squirrel fish follows the traditional method — crisp fronds, a balanced sauce — and it's the pick if you want a calmer meal away from the pedestrian streets. Book ahead, as seating is limited.
Squirrel fish is easy to find across Suzhou's old town — almost every Su-cuisine restaurant around Guanqian Street and along the canal lanes of Pingjiang Road (平江路) and Shantang Street (山塘街) has it on the menu. If you'd rather not queue for the famous names, walk into a local place busy with Chinese diners and you'll rarely be disappointed. Look for 松鼠鳜鱼 or 松鼠桂鱼 on the menu and point. On the main canal-street drag, though, expect flavour and prices tuned more for tourists — try ducking into a side lane.
