Korea (Joseon dynasty)
Japchae
Glass noodles tossed with sesame oil, soy, and a rainbow of julienned vegetables — Korea's celebration banchan, originally a noodle-less royal court dish.
Sweet potato starch, not wheat.
Korean glass noodles (*dangmyeon*) are made from sweet potato starch — not wheat, not rice, not mung bean. The result is springy, slightly chewy, deeply translucent, and able to soak up sesame oil without going gummy. A japchae made with Chinese mung-bean glass noodles is technically possible but reads softer; the dangmyeon is what gives the dish its bounce.

Japchae
Glass noodles tossed with sesame oil, soy, and a rainbow of julienned vegetables — Korea's celebration banchan, originally a noodle-less royal court dish.
A dish older than the noodle. Japchae (잡채, “mixed vegetables”) appears in early Joseon dynasty (15th century) court records as a vegetables-only royal banquet dish — no noodles, no meat, just an arrangement of seasoned, separately-cooked vegetables. The glass noodles came later, around the early 20th century when dangmyeon production from China and Korea industrialised, and the noodles absorbed the dish so thoroughly that today’s japchae is unrecognisable without them.
Japchae sits in an unusual place in Korean cuisine: equally welcome as a side dish (banchan) on a daily table and as a centrepiece at celebration meals. Korean New Year, weddings, Chuseok (autumn harvest festival), and 60th-birthday parties all serve large platters of japchae. The dish belongs to both the everyday and the ceremonial register — a status few Korean dishes share.
Each vegetable stir-fried separately.
The Korean technique is to cook each component on its own — spinach blanched, mushrooms sautéed, carrot julienne stir-fried, onion caramelised, beef marinated and fried — then combined at the end with the warm noodles and the sesame-soy dressing. This is more work than a single-wok stir-fry but it's why each vegetable in the bowl retains its colour and character; a single-pan version turns into a brown tangle.
