Japchae
Glass noodles made from sweet potato starch, stir-fried separately from julienned vegetables and beef, then tossed together with soy sauce and sesame oil. The noodles stay chewy and translucent rather than soft like wheat noodles.
Where it comes from
Japchae is often traced to early 17th century Korean royal court cooking, an origin story repeated more often than verified, originally made without any noodles at all, just vegetables. The sweet potato starch noodles were added later, once that starch became commercially available.
What cooks argue about
Cooks argue over cooking each vegetable and the beef separately before combining, which preserves distinct textures and colors, against tossing everything together in one pan, which is faster but blurs the individual flavors.
