What makes sweet potato starch noodles, aka glass noodles, so unique? This particular noodle is chewier than most, creating a fun texture in dishes. These starchy noodles are commonly used in japchae, a Korean stir fry dish with vegetables. Get creative with Surasang's noodles and use them in soups or chilled salads. Don't forget to add a side of kimchi for a more authentic dish.
