Sweet potato starch noodles, also known as dangmyeon or glass noodles, are a popular ingredient in Korean cuisine. These translucent noodles are made from sweet potato starch and have a chewy and slightly slippery texture. They are often used in dishes like Japchae (stir-fried noodles), Tangpyeongchae (cold salad), and various soups. Sweet potato starch noodles are gluten-free and a great option for those with dietary restrictions.
