Dong Ting Hu Chou Gui Yu (洞庭湖臭鳜鱼)

The Dongting Lake region of Hunan has long traded in preserved fish, and chou gui yu — a mandarin fish intentionally fermented for several days until it develops an assertive, funky aroma — is the pride of the region. Once braised in chilli and rice wine, the smell transforms into a haunting umami richness that has made it one of Hunan's most celebrated heirloom dishes, served at family gatherings and ancestral festivals.

Serves: 4

Ingredients

• 1 whole mandarin fish (gui yu) or firm white fish such as sea bream, about 800g (1.75 lb), gutted and scored (fresh is fine; curing step below)
• 2 tsp coarse salt (for curing)
• 4 cloves garlic, sliced
• 3cm piece ginger, julienned
• 4 pao jiao (pickled red chillies) or fresh red chillies, sliced
• 2 tbsp (30ml) Shaoxing rice wine
• 1 tbsp (15ml) light soy sauce
• 1 tsp sugar
• 200ml (0.8 cup) pork or fish stock
• 3 tbsp (45ml) neutral oil
• 2 spring onions, cut into batons
• 1 tsp sesame oil
• Small handful fresh coriander

Instructions

1. For a mild curing: rub the fish inside and out with coarse salt. Wrap in cling film and refrigerate for 24 hours. Rinse and pat dry before cooking. (Skip this step for a fresher version.)
2. Score the fish on both sides at 2cm intervals. Heat oil in a wide heavy pan over medium-high heat. Fry the fish 3–4 minutes per side until the skin is golden and crisp. Remove.
3. In the same pan, fry garlic, ginger, and chillies over medium heat for 1 minute. Add Shaoxing wine — let it bubble — then stir in soy sauce, sugar, and stock.
4. Return the fish to the pan. Spoon sauce over. Add spring onion batons. Cover and braise over low heat for 15–18 minutes, basting every 5 minutes, until the flesh flakes easily from the bone.
5. Drizzle with sesame oil and scatter coriander. Serve directly from the braising pan with steamed rice.

Cook's Notes: The 24-hour salt cure mimics the traditional fermentation at a mild, approachable level for home cooks. Traditionalists use a 3–5 day room-temperature cure; this creates a more pronounced funky flavour beloved in Hunan.
