Dangmyeon, "glass noodles" in Korean, are made from sweet potatoes. When cooked they become translucent with a chewy texture. Perfect for stir-fry and soup.
Japchae literally translates to "mixed and stirred" and there's not much more than that.
Simply mix Obap Sweet Potato Noodles with vegetables and marinated beef, creating a stir-fry that you'll be sure to cook again and again.
