Anhui Stinky Mandarin Fish
Chou gui yu: Anhui's most famous (and notorious) dish. Fresh mandarin fish slightly fermented for 6–7 days at room temperature until mildly pungent, then red-braised or steamed. The controlled fermentation creates a distinctive creamy texture and complex flavour unlike fresh fish. Different from spoilage — it is intentional transformation.

The Method
1
Rub the cleaned whole fish thoroughly with fine salt on all surfaces, inside and out. Place in a non-reactive vessel — ceramic or glass — and keep at a cool room temperature of 15–20 °C for 6–7 days. After 6 days, assess: the fish should smell distinctly pungent but not putrid, and the flesh should feel firm yet yield slightly under pressure. At day 7, structural integrity begins to decline — do not exceed this window.
2
Remove the fermented fish. Rinse briefly under cold running water and pat dry. The surface will appear slightly tacky. Score the flesh on both sides in two or three places to allow the braise to penetrate.
3
In a wok or wide braising pan, combine the soy sauce, Shaoxing wine, sugar, and ginger slices with enough water to come one-third up the side of the fish. Bring to a simmer over medium heat, stirring until the sugar has dissolved — the liquid should smell of soy and wine and run a deep amber.
4
Lay the fish in the simmering braise. Cover and cook over medium-low heat, turning the fish once carefully at the halfway point. Baste repeatedly. The braise is ready when the liquid has reduced to a glossy coating that clings to a spoon and the flesh has taken on a deep reddish-brown colour. This typically takes 20–25 minutes.
5
Transfer to a serving plate. Spoon the reduced braising liquid over the fish. The cooked flesh should be creamy in texture — distinctly softer and more unctuous than fresh fish — with a deeply savoury aroma that has lost the sharp pungency of the raw fermented state. Serve immediately with steamed rice.

Quality Hierarchy
01
Reserve — A live or day-boat mandarin fish, salted and fermented under controlled cool conditions for the full 6–7 days; the dish in its Huizhou original form.
02
Estate — A very fresh whole mandarin fish from a reputable fishmonger, fermentation conducted with close temperature monitoring throughout.
03
Market — Fresh whole mandarin fish available at a Chinese wet market or Asian fishmonger, fermented carefully at the lower end of the temperature range to reduce risk.
04
House — The closest firm-fleshed freshwater fish available — perch or sea bass may be substituted — though the resulting dish will lack the characteristic creamy texture and umami depth of properly fermented guiyu.

Sensory Tests
◇Smell. After 6–7 days the fish emits a distinct, controlled pungency — sharp but not rotten or ammoniacal; an ammoniacal or putrid smell indicates spoilage and the fish must be discarded.
◇Touch. The fermented flesh yields slightly under a firm finger press but holds its shape; collapse or sliminess indicates over-fermentation.
◇Sight. The finished braise coats the fish in a glossy, deep reddish-brown glaze that sheets slowly from the back of a spoon.
◇Smell. Once cooked, the sharp fermentation smell resolves into a deeply savoury, complex aroma — the alarming raw scent should be substantially absent from the finished dish.
◇Where it lives or dies. The fermentation must be held at 15–20 °C for exactly 6–7 days with salt applied from the outset — too warm or too long produces spoilage rather than the controlled transformation the dish requires.

What to Pour
A regional rice wine (huangjiu) in the style of Shaoxing — its mellow, slightly sweet oxidative character bridges the dish's intensity; alternatively, a dry aged-style sake carries similar logic. The dish's funky depth would overwhelm delicate whites.
