Yongzhou Blood Duck
“A duck stir-fried hot, sour and bloody — its own fresh blood whisked in at the end thickens the sauce a deep mahogany.”
The bite
Dark, glossy duck pieces under a sauce so reduced it looks lacquered. The blood reads not as iron but as depth — it rounds out the chile heat and the rice-vinegar sharpness, the way demi-glace rounds a French sauce. You bite through crisp browned skin, render-soft fat, then meat that fell off the bone twenty minutes ago. Ferocious with cold beer and white rice. Polarizing if you're not used to it; canonical in Yongzhou.
Where it comes from
From Yongzhou in the south of Hunan, where Tang-dynasty records mention duck cooked with its own blood. The dish is locked to the region — outside Yongzhou it's mostly served by transplants. Local lore ties it to a Tang general's army feast on the night before battle, but the technique itself is older and shared with Yao mountain villages nearby that cook duck the same way.
What makes it work
The blood is plasma plus suspended cells — when you add it off the heat to a hot pan, the residual ~80°C is enough to denature albumin and bind the sauce, but not so hot it scrambles into liver-textured curds. That's why the wok comes off the burner first. Salt and rice wine in the collection bowl prevent fibrin from clotting in the 20 minutes between slaughter and finish; without them you can't pour the blood at all.

When slaughtering a 1.5kg fresh duck (or asking the butcher), collect the blood in a bowl with 30ml rice wine and 5g salt, stirring constantly so it doesn't clot. Cover and reserve at room temperature.

Chop the duck through the bone into 3cm pieces. Rinse briefly to remove bone shards. Pat dry — water in the wok ruins the sear.

Heat 60ml oil in a heavy wok until smoking. Add ginger, garlic, dried chiles and the white parts of scallions. Add duck and stir-fry hard over high heat for 8 minutes — the skin must brown and the fat must render.

Splash in 60ml rice wine, then 2 tbsp light soy and 1 tbsp dark soy. Add 200ml hot water, fresh red and green chiles, a stick of bruised lemongrass and a bay leaf. Cover and simmer 20 minutes until duck is tender.
- 54 min
Uncover, raise heat, reduce sauce until 4 tbsp remain in the wok. Add a splash of rice vinegar.
- 62 min
Take wok off the heat. Stir the duck blood once and pour in slowly while tossing — it will set into a glossy mahogany glaze in 30 seconds. Do not return to high heat or it curdles. Scatter scallion greens and serve with rice.
