The majority of Korea's "sundae" (순대) can be categorised as blood sausage. The most common type of "sundae" is made of sweet potato noodle ("dangmyeon"), barley, and pig's blood, but some variants contain sesame leaves, green onion, fermented soy paste ("doenjang"), sweet rice, kimchi, and bean sprouts, in addition to the common ingredients. The Korean sundae is wrapped with pig's intestines. The addition of sweet potato noodle is a more modern addition to the dish. There is another Korean food called "seonji" which is cow blood that has been boiled in soup. It looks like the Blodpudding of Sweden.
