Yongzhou blood duck (永州血鸭, yǒng zhōu xuè yā) is one of the most legendary dishes of Hunan cuisine, originating from the ancient city of Yongzhou in southern Hunan. Chopped duck pieces are stir-fried with ginger, garlic, and dried chilies, then finished with fresh duck blood that coats every piece in a deep, glossy, wine-red sauce. The result is rich, savory, spicy, and deeply aromatic — a dish that is truly unforgettable. It is said that the dish was invented by a Qing Dynasty chef who accidentally spilled duck blood into a stir-fry, and the rest is culinary history.
The blood of Yongzhou
Yongzhou blood duck is more than just a dish — it is a cultural icon of southern Hunan. The tradition of cooking with fresh blood dates back thousands of years in China, and it reflects a philosophy of using every part of the animal. In Yongzhou, every family has their own secret recipe, passed down through generations. The key is the freshness of the blood — it must be mixed with rice vinegar to prevent clotting, and stirred into the dish at the exact right moment. When done properly, the blood creates a smooth, velvety sauce that clings to every piece of duck, giving it that signature deep red color and rich, iron-rich flavor. The dish is often served at festivals, weddings, and important family gatherings, where it is considered a sign of respect and hospitality.
The name "tiger skin" refers to the distinctive appearance of the peppers after frying. As the skin chars in irregular patches against the remaining green flesh, it creates a striped, mottled pattern reminiscent of a tiger's coat. But this isn't just a clever name — the charring is essential to the flavor. The blistered skin develops a deep, smoky sweetness that balances the bright heat of the pepper and the tang of the vinegar sauce. This is a classic Xiangjiang River school dish: quick, bold, and rooted in home cooking. You'll find it on dinner tables across Hunan every week, often as the only vegetable dish alongside a meat stir-fry and a bowl of soup. It is the very definition of "simple but perfect."
Ingredients
The key ingredients are the duck and the fresh blood. For the most authentic result, use a whole duck and collect the fresh blood when it is butchered — this is how it is done in Yongzhou.
- 1 whole duck (about 1.5 kg), chopped into small pieces
- 200 ml fresh duck blood (mixed with 1 tbsp rice vinegar to prevent clotting)
- 10-15 dried red chilies, cut into sections
- 6-8 garlic cloves, sliced
- 1 large piece ginger, sliced
- 4 scallions, cut into sections
- 3 tbsp cooking wine (Shaoxing wine)
- 2 tbsp light soy sauce
- 1 tbsp dark soy sauce
- 1 tsp sugar
- 1/2 tsp salt
- 3 tbsp cooking oil
- 1/2 cup water or chicken stock
- 1 tsp sesame oil
Step-by-Step Instructions
-
Prepare the duck and blood. Rinse the duck pieces thoroughly and pat dry with paper towels. The duck should be chopped into small, bite-sized pieces — about 3 cm each — so they cook evenly and absorb flavor well. If you have fresh duck blood, mix it with 1 tablespoon of rice vinegar immediately and stir gently to prevent clotting. Set it aside at room temperature. If you do not have fresh blood, you can use coagulated duck blood cut into small cubes, but the texture and flavor will be different.
-
Blanch the duck. Bring a pot of water to a boil. Add the duck pieces and blanch for 2 to 3 minutes. This removes impurities and excess fat. Drain and rinse the duck under warm water. Pat dry with paper towels. This step is important for a clean-tasting final dish — do not skip it.
-
Stir-fry the aromatics. Heat 3 tablespoons of oil in a wok or large frying pan over medium-high heat. Add the ginger slices and stir-fry for 30 seconds until fragrant. Add the garlic and dried red chilies, and stir-fry for another 15 seconds. Do not let the garlic burn — it should be golden, not brown. The kitchen should fill with the aroma of ginger, garlic, and chilies.
-
Braise the duck. Add the blanched duck pieces to the wok. Turn the heat up to high. Stir-fry vigorously for 3 to 4 minutes, until the duck is lightly golden on all sides. Add the cooking wine and let it sizzle and evaporate for a few seconds. Add the light soy sauce, dark soy sauce, sugar, and salt. Stir everything together. Pour in the water or chicken stock — the liquid should come about halfway up the duck. Bring to a boil, then reduce heat to medium-low. Cover and simmer for 25 to 30 minutes, stirring occasionally, until the duck is tender and the sauce has reduced.
-
Add the blood. This is the most important step. Stir the duck blood well — it should be liquid and smooth, with no clots. Turn the heat down to low. Slowly pour the blood into the wok while stirring constantly in one direction. Keep stirring gently for 1 to 2 minutes, until the blood thickens and coats every piece of duck. The sauce should be thick, glossy, and deep wine-red in color. Do not overcook the blood or it will become grainy. If the sauce is too thick, add a splash of water. If it is too thin, simmer for a minute longer.
-
Finish and serve. Add the scallion sections and drizzle with sesame oil. Give everything a final gentle toss. Transfer to a serving plate or bowl. Serve immediately with steamed white rice — the rich, spicy, blood-coated duck is incredible over rice. Each piece should be coated in a thick, glossy, deep red sauce. The flavor is rich, savory, slightly gamey, spicy, and deeply aromatic. It is not a dish for the faint of heart — but for those who love bold flavors, it is unforgettable.
Secrets to authentic Yongzhou blood duck
- Use fresh blood if possible. Fresh duck blood mixed with rice vinegar gives the authentic smooth texture and deep flavor.
- Low heat for the blood step. High heat causes the blood to curdle and become grainy. Low and slow = smooth sauce.
- Stir in one direction. Constant stirring while pouring the blood creates a smooth, emulsified sauce.
- Do not skip the blanching. Blanching the duck removes impurities and gives the dish a cleaner, brighter flavor.
Variations
While the classic version is definitive, there are a few regional variations of this famous dish.
With sour bamboo shoots
In some parts of Yongzhou, sour bamboo shoots (suan sun) are added to the dish. The tanginess of the fermented bamboo cuts through the richness of the duck and blood, adding another layer of flavor.
With fresh chilies
For a brighter, fresher flavor, use fresh red chilies instead of dried ones, or a mix of both. Fresh chilies add a different kind of heat and a vibrant red color.
Blood cake version
If fresh liquid blood is not available, you can use coagulated duck blood (blood tofu) cut into small cubes. Add them during the last few minutes of braising. The texture is different — more like tofu than sauce — but still delicious.

Frequently Asked Questions
Is it safe to eat duck blood?
Yes, when handled properly, duck blood is perfectly safe to eat. It is a common ingredient in many cuisines around the world, including Chinese, Vietnamese, and British (black pudding). The key is freshness — the blood should come from a healthy, properly butchered duck, and it should be used the same day. Mixing it with rice vinegar or salt helps prevent bacterial growth. If you are unsure about the source or freshness, you can use coagulated duck blood (which has been cooked) instead. When cooked thoroughly, it is as safe as any other meat product.
What does duck blood taste like?
Duck blood has a mild, iron-rich flavor that is often described as earthy or minerally. It is not gamey or strong — the flavor is subtle and savory. When used as a sauce (as in this dish), it mainly adds richness, depth, and a velvety texture rather than a strong blood taste. The soy sauce, ginger, garlic, and chilies provide most of the flavor, while the blood adds body and that signature deep red color. If you have ever had blood sausage or black pudding, it is a similar flavor but much milder and smoother.
Can I use chicken instead of duck?
You can, but the dish will not be the same. Duck has a richer, slightly gamey flavor and more fat, which stands up to the strong flavors of the blood and chilies. Chicken is milder and would get lost. If you must substitute, use chicken thighs (not breast) for more flavor and moisture, and consider adding a little extra fat. But if at all possible, use duck — it is worth seeking out. The dish is called blood duck for a reason — duck is essential to its character.
Why is it called blood duck?
The name is literal — it is duck cooked with blood. But there is also a legend behind it. According to one story, the dish was invented during the Qing Dynasty by a chef in Yongzhou who was preparing a duck stir-fry for a local official. He accidentally knocked over a bowl of fresh duck blood into the wok. Instead of starting over, he stirred it in and served it. The official loved it so much that he asked for it again, and the dish was born. Whether the legend is true or not, the dish has been a Yongzhou specialty for hundreds of years.
