Goguma-muk is a traditional Korean dish made from sweet potato starch. It is a type of jelly-like food that is often served cold and can be enjoyed as a side dish or dessert. The texture is smooth and slightly chewy, making it a unique addition to various meals. Typically, goguma-muk is prepared by mixing sweet potato starch with water and then cooking it until it thickens. Once cooled, it can be cut into cubes or slices. It is often served with a drizzle of soy sauce or sesame oil, and sometimes garnished with sesame seeds or green onions for added flavor.
