What is "dotorimuk"

__NOTOC__ Dotorimuk (also spelled tot'orimuk) or acorn jelly is a Korean food which is a jelly made from acorn starch. Although "muk" means "jelly", when used without qualifiers, it usually refers to dotorimuk. The practice of making dotorimuk originated in mountainous areas of ancient Korea, when abundant oak trees produced enough acorns each autumn to become a viable source of food. Like other muk, dotorimuk is most commonly eaten in the form of dotorimuk muchim (도토리묵무침), a side dish in which small chunks of dotorimuk are seasoned and mixed with other ingredients such as slivered carrots and scallions, garlic, soy sauce, sesame oil, red chili pepper powder, and sesame seeds.
