Korean sundae is a traditional blood sausage that usually consists of rice, glass noodles (dangmyeon), and pig’s blood, while the variations may also incorporate barely, bean sprouts, kimchi, perilla leaves, soybean paste, or scallions. Some regional varieties may even consist of squid or fish.

Sundae can be steamed and enjoyed on its own, but it is also incorporated into various dishes such as the hearty sundaeguk soup or the sundae bokkeum stir fry. It is believed that sundae originated sometime in the Goryeo period (918–1392).
