A theatrical table-cooked course from the Baling Whole-Fish Banquet: snakehead fish from Dongting Lake is cut with a diagonal blade into paper-thin slices arranged on platters in butterfly formations, then blanched by diners at the table in a simmering broth of chicken stock, fish bones, ham, bamboo shoots and dried mushrooms — the slices unfurling into wings as they cook.
Butterfly Crossing the River — also known as 'Butterfly Drifting Across the Sea' (蝴蝶飘海) — is one of the most celebrated courses within the Baling Whole-Fish Banquet codified by master chef Zhang Keliang in Yueyang in 1956. The dish draws on the lakeside tradition of eating fresh-caught fish with minimal cooking, elevated to banquet formality through meticulous knife-work and a refined broth. The name is as much poetry as description: the image of translucent fish slices drifting open across the broth's surface channels the Dongting Lake aesthetic that permeates Yueyang's culinary identity — still water, clear light, and things of grace passing through.
Fish slices emerge from the broth barely opaque, still trembling, their flesh so fine-grained it dissolves at the lightest pressure of the tongue. Dipped in a few drops of Chinkiang black vinegar and chilli oil, the clean lake sweetness of the snakehead blooms through the acid and heat — tasting of cold water and clear light over Dongting, with a springy resilience that separates it entirely from farmed fish.
Snakehead (乌鳢) is a predatory fish with predominantly fast-twitch white muscle fibres and very low intramuscular fat (approximately 0.8 g per 100 g), giving it a firm, dense flesh that holds together during the brief blanch without crumbling. The diagonal blade — held at approximately 30 degrees to the fillet surface — cuts across multiple myomere segments simultaneously, severing the collagen sheets between them; when a thin slice enters broth at 85–90 °C, the surface proteins (myosin) denature and contract faster at the exposed cut edges than in the thicker interior, generating an asymmetric contractile force that causes each slice to curl and fan open — producing the 'butterfly wing' shape. Blanching for only 15–20 seconds raises the interior to just above 60 °C, where myosin coagulates but collagen has not yet solubilised, locking in the fish's characteristic spring and lake sweetness.
Variations
Grass carp back loin — a more affordable Dongting Lake alternative — can be substituted for snakehead, yielding a softer but still acceptable texture. Some restaurants replace fish slices with thin-cut pork kidney (猪腰), producing a sharply different mouthfeel using the same table-blanching format. A winter version enriches the broth with Dongting artemisia (蒿草) and winter melon, giving a clearer, more herbal base. In the original Baling banquet context, the dish is served mid-meal as the dramatic theatrical peak after the stir-fried courses.

How it's made
8 steps · 25 min
- 110 min
Scale and fillet the snakehead; using a sharp blade held at approximately 30 degrees to the fillet surface (diagonal cut), slice the fillets paper-thin — about 2 mm thick; the oblique angle crosses the myomere rings, which will fan open like butterfly wings when heated.
Watch outHold the blade at a shallow 30 degrees and slice two millimeters thin across the muscle rings — this angle is what makes the slices fan open like wings.
- 25 min
Arrange slices on two white ceramic plates in a butterfly formation, placing the fish head and tail at either end of each plate as decorative accents; season slices lightly with salt, Shaoxing wine and a few slices of ginger; rest for 10 minutes.
- 320 min
Prepare the broth: simmer reserved fish bones, head skin and fins with chicken stock, ginger slices and spring onion knots for 20 minutes; strain through a fine sieve into a stainless-steel table pot.
- 45 min
Cut winter bamboo shoots into thin comb-shaped slices; slice smoked ham and soaked dried mushrooms into thin strips.
- 53 min
Bring broth to a rolling boil; add bamboo shoots, ham and mushrooms; season with salt and white pepper; taste and adjust.
- 62 min
Transfer the broth pot to a small alcohol burner at the centre of the dining table; arrange condiment bowls: Chinkiang black vinegar, chilli oil, ground white pepper, minced garlic.
- 715 min
Diners use chopsticks to lower individual fish slices into the simmering broth and blanch for 15–20 seconds until the slices turn from translucent to opaque and curl open into a butterfly shape; lift immediately and dip in chosen condiments.
Watch outBlanch each slice just fifteen to twenty seconds, until it turns from clear to milky white and curls open — pull it the instant it curls, a beat more and it toughens.
- 85 min
As the meal progresses, add bean sprouts, fresh coriander and water spinach to the enriching broth; the liquid grows sweeter and more complex with each batch of fish.
