A Rich History of Cooking with Blood
For millennia, people have used animal blood in cooking, often as a nutritious and efficient way to use every part of a slaughtered animal in a practice known as 'nose-to-tail' eating. This tradition not only prevented waste but also provided a source of high-quality protein and iron. The use of blood varies significantly across different cultures, depending on available resources, local tastes, and specific culinary traditions. It serves many functions, from a binding agent in sausages and a thickener in sauces to a centerpiece ingredient in soups and congealed cakes.
Blood Sausages from Around the World
One of the most common applications for blood is in sausage-making. A variety of fillers and seasonings are combined with blood before being cooked, creating a dense, savory product.
European Blood Sausages
- Black Pudding (UK & Ireland): A distinctive blood sausage made from pork blood, pork fat, and cereal, typically oatmeal or barley groats. It is often a key component of a traditional full English breakfast.
- Morcilla (Spain, Mexico, and Latin America): A sausage where fillers can include rice, onions, paprika, and sometimes sweet additions like pine nuts or raisins, depending on the region.
- Boudin Noir (France): A classic French delicacy featuring a high proportion of pig's blood mixed with pork fat and seasonings.
- Blutwurst (Germany): A German blood sausage that often incorporates diced bacon, pork rind, and fillers like barley.
- Kaszanka (Poland): A Polish blood sausage traditionally made with pig's blood and buckwheat kasha.
Asian and American Blood Sausages
- Sundae (Korea): A popular street food made by stuffing cow or pig's blood mixed with ingredients like sweet potato noodles and barley into pig intestines.
- Pinuneg (Philippines): A native blood sausage made with minced pork and innards, from the highlands of Luzon.
- Mutura (Kenya): A traditional Kenyan blood sausage prepared with minced meat, spices, and blood encased in the animal's stomach or intestines.
Soups, Stews, and Sauces
Beyond sausages, blood lends its rich, savory character to many liquid-based dishes.
Savory Strews
- Dinuguan (Philippines): A savory pork blood stew, often cooked with offal (like liver and intestines), vinegar, and chili peppers.
- Cabidela (Portugal & Brazil): A dish where chicken or rabbit is cooked in its own blood with vinegar and spices, resulting in a tangy, thick sauce.
- Haejangguk (Korea): A beef broth-based hangover soup that often includes solidified blood curd.
Flavorful Soups
- Svartsoppa (Sweden): A black soup traditionally made with goose blood, served in the southern region of Skåne.
- Czernina (Poland): A Polish blood soup featuring duck or goose blood, often prepared with a sweet and sour flavor.
Sauces and Thickeners
- Coq au Vin (France): In some traditional preparations, chicken blood is added at the end to thicken and enrich the sauce.
Coagulated Curds and Cakes
Animal blood can be congealed into solid, tofu-like blocks or cakes, which are then used in various recipes.
Asian Blood Curds
- Blood Tofu (China): Made with coagulated duck or pig's blood, which is then cut into cubes and used in soups like hot pot.
- Pig's Blood Cake (Taiwan): A street food snack made from sticky rice and pig's blood, steamed, then often fried and coated in peanut flour.

Health and Safety Considerations
Blood-based foods offer a significant nutritional boost, particularly their high protein and iron content. However, safety and health precautions are critical. Raw blood can carry pathogens, which is why proper hygiene during collection and thorough cooking is essential. For most people, consuming cooked, hygienically sourced blood products is not a health risk. However, individuals with hemochromatosis, a condition causing the body to absorb too much iron, should consult a doctor before consuming large amounts of iron-rich foods.
Religious Dietary Prohibitions
It is important to note that certain religions, such as Judaism and Islam, strictly prohibit the consumption of blood. These dietary laws mean that many blood-based foods are considered non-kosher or haram. For this reason, consumers should be aware of ingredients when considering these dishes, and producers must provide proper labeling.
Conclusion
The question of which foods contain blood reveals a fascinating intersection of culture, resourcefulness, and flavor. From the hearty black puddings of Britain to the spicy stews of the Philippines, and the savory sausages of Spain, blood has played a significant role in global cuisine for centuries. These dishes are a testament to the creativity and practicality of traditional cooking, turning a valuable co-product into a delicious and iron-rich meal. Exploring these foods offers a unique taste of culinary heritage and an appreciation for the diversity of global gastronomy.
