Steam-Grilled Salmon with Miso (ちゃんちゃん焼き, Chan-chan-yaki)

Chan-chan-yaki begins with autumn salmon. Not a delicate little fillet fussed over with tweezers, but a sturdy piece of fish laid over cabbage and onions, then covered and cooked until everything gives itself to the miso. This is Hokkaido comfort food, fisherman food, and it has the good manners to be ready on a weeknight.

The method is simple, though people make it sound larger because an iron plate is involved. We brown the salmon first so the skin and surface take on flavor, then we set the vegetables beneath it and cover the pan. The lid matters. It traps the moisture from the cabbage and onion, so the fish steam-grills rather than dries, and the miso sauce loosens into every fold without needing a heavy hand.

The one detail that decides it is the miso. It should be sweet-salty and loose enough to spread, not so thick that it sits on top like paste. Red or blended miso gives the dish backbone, sake wakes it up, mirin and a little sugar round it, and butter at the end belongs here, especially in Hokkaido. Nothing hidden. If the salmon is glistening fresh and in its 旬 (shun), at its prime, the sauce is there to carry it, not bury it.
