Tiết canh

The freshly drawn blood is collected in a bowl, and prevented from premature coagulation (hãm huyết), by mixing it with some fish sauce of certain proportions, usually three to five soup spoons of fish sauce for one quart (approximately 1 liter) of blood. Finely chopped meat such as cooked duck innards (gizzards, for example) and duck meat are put in a shallow dish along with a sprinkling of crushed peanuts and chopped herbs such as Vietnamese coriander, mint, etc. The blood and fish sauce mixture is then diluted with some watery broth left from cooking the meat and/or gizzards to promote blood coagulation, then quickly poured into the prepared meat dish. The finished dish can be kept cool in the refrigerator, which allows the blood to maintain its coagulated state, when immediate consumption is not called for right away. If the dish is removed from the refrigerator and left to sit at room temperature for a while the blood will return to a liquid state.

Raw pig's blood often contains swine bacteria, and ingesting them may cause severe bacterial infections.[1] For example, a streptococcus bacterium infection may cause respiratory decline, blood contamination, and severe necrosis in arms and legs, and is potentially fatal. In Vietnam, there are reports of human casualties after eating raw blood pudding.[2]
