Description
Donburi (丼, large bowl) dishes are Japan's ultimate one-bowl meals — proteins and sauce served over steaming rice in a deep ceramic bowl. The two most beloved: katsudon (カツ丼) — breaded pork cutlet simmered briefly in dashi-soy-mirin with onion and egg; and oyakodon (親子丼, parent-and-child bowl) — chicken and egg simmered together in the same sauce, the name referring to the poetic/grim connection between parent (chicken) and child (egg). The technical challenge in both: the egg must be set to a specific consistency — barely cooked, still flowing with deep yellow yolk color, draped over the protein.
