Tteokbokki: Sauce Coating and Rice Cake Technique
Tteokbokki — spicy rice cakes — is the defining street food of modern Korean cooking: cylindrical rice cakes (tteok) coated in a sweet, spicy, sticky gochujang-based sauce. The technique is entirely about sauce reduction and coating — the rice cakes contribute texture and neutral starchiness; the sauce provides everything else.
Cylindrical rice cakes simmered in a gochujang, gochugaru, soy sauce, and sugar-based sauce until the sauce has reduced to a thick, sticky glaze that coats each rice cake completely. Fish cakes and other additions are standard.
