These days, miso-marinated black cod is almost synonymous with Nobu Matsuhisa's New York restaurant, though he by no means invented the dish. It stems from a traditional Japanese preparation called kasuzuke, in which fish and vegetables are marinated in the leftover lees from sake production before being broiled or grilled. This is the fish dish to pull out when you're ready to blow away your spouse or dinner guests, but don't want to put more than five minutes of effort into making dinner. Five minutes. Really.
