당면 is a type of transparent noodle made from starch, commonly used in Korean cuisine. It is primarily made from sweet potato starch, which gives it a chewy texture and a slightly sweet flavor. 당면 is often used in dishes like 잡채 (japchae), where it is stir-fried with vegetables and meat, absorbing the flavors of the ingredients. These noodles are gluten-free, making them a popular choice for those with gluten sensitivities. When cooked, 당면 becomes soft and slippery, making it a versatile ingredient in soups, salads, and stir-fries. Its unique texture and ability to soak up sauces enhance the overall taste of various dishes.
