Types of Asian Noodles

Sweet potato noodles — a Korean favorite that star in japchae, a chilled salty-sweet noodle dish — are made with sweet potato starch and are similar in appearance to bean thread noodles. Sold dried, these light-gray, brittle noodles cook up exceptionally fast and are prized for their glossy, translucent appearance and firm, chewy, slippery texture once cooked.
