The history of duck blood soup dates back centuries and can be traced to different parts of the world. While it is difficult to pinpoint its exact origins, various cultures have embraced this dish and adapted it to their own culinary traditions.


In Asian cuisine, duck blood soup has been a staple for many centuries. In China, it is believed to have originated during the Song Dynasty (960-1279 AD) as a way to make use of the entire duck and reduce food waste. The soup was especially popular among the lower classes as it provided a cheap source of protein and nutrients. Over time, the dish gained popularity and became a favorite among the masses.


In Vietnam, duck blood soup, known as bun rieu cua, has a long history and is considered a beloved comfort food. It is believed to have been introduced during the period of Chinese domination in the country. Vietnamese cooks adapted the dish, adding their own unique blend of spices and herbs to create a flavorful and aromatic version of duck blood soup.


In Europe, Poland has its own version of duck blood soup known as czernina. This traditional soup has deep roots in Polish culinary heritage and was typically served during special occasions and holidays. Czernina is made with duck blood, vinegar, dried fruits, and aromatic spices, resulting in a sweet and sour flavor profile.


The popularity of duck blood soup has transcended borders and cultures, with each region putting its own spin on the dish. While the precise reasons for its creation may differ, one common thread is the resourcefulness of utilizing every part of the duck and turning what may be considered waste into a flavorful and nutritious meal.

Ingredients and Preparation

The ingredients used in duck blood soup can vary depending on the regional variations and specific recipe preferences. However, there are a few key components that are commonly found in this flavorful soup.


The main ingredient, of course, is the duck blood itself. The blood is typically collected by carefully slaughtering the duck and capturing the blood in a bowl or container. It is important to note that the blood is usually coagulated before being added to the soup, giving it its distinctive texture.


In addition to the duck blood, the soup will often feature a variety of other ingredients such as meat, vegetables, and spices. Popular additions include duck meat, tofu, mushrooms, bean sprouts, onions, garlic, ginger, chili peppers, and cilantro. These ingredients not only add flavor and texture but also contribute to the overall nutritional profile of the soup.


The preparation of duck blood soup can vary depending on the culinary tradition and recipe being followed. However, the general process typically involves the following steps:

  1. Coagulating the duck blood: The collected duck blood is coagulated by adding vinegar, lime juice, or other acidic ingredients. This causes the blood to solidify into a gelatinous form.
  2. Preparing the broth: A flavorful broth is created by simmering duck bones, vegetables, and spices in water. This helps to infuse the soup with rich flavors.
  3. Adding ingredients: Once the broth is ready, the coagulated duck blood is added along with other desired ingredients such as meat, vegetables, and spices.
  4. Simmering and seasoning: The soup is simmered over low heat to allow the flavors to meld together and the ingredients to cook. Additional seasonings like fish sauce, soy sauce, or herbs may be added at this stage.
  5. Serving: Duck blood soup is typically served hot and garnished with fresh herbs, bean sprouts, or chili oil to enhance the taste and presentation.

It’s worth noting that different cultures and regions have their own unique variations and techniques when it comes to preparing duck blood soup. These variations contribute to the diverse range of flavors and textures found in this intriguing dish.
