Sablefish marinated in sweet miso and sake, broiled until the edges caramelize into something close to candy.

Misoyaki butterfish (usually sablefish or black cod) shows up on white tablecloths and in bento boxes alike — a legacy of Japanese immigration to Hawai'i, where the buttery, high-fat fish takes beautifully to a sweet miso marinade and a hot broiler.

The trick is patience: the marinade needs at least a full day to really work into the fish, and the broiler needs watching, since the sugar in the marinade goes from caramelized to burnt in under a minute.

How fo’ make ’um

  1. Whisk the miso, sugar, mirin, and sake together in a small pot over low heat just until the sugar dissolves. Let cool completely.
  2. Pat the fish fillets dry and coat them thoroughly in the cooled marinade. Place in a container or zip bag, pressing out excess air.
  3. Marinate in the refrigerator at least 24 hours, up to 3 days — the longer it sits, the deeper the flavor.
  4. When ready to cook, scrape off most of the excess marinade (a thin coating is enough; too much burns before the fish cooks through) and place fillets skin-side down on a foil-lined broiler pan.
  5. Broil on high, watching closely, 6–8 minutes, until deeply caramelized and lightly charred at the edges. The fish should flake easily.
  6. Rest a minute before serving over rice — the fish is delicate and falls apart easily when hot.

Local tips

  • Don't skip the marinade scrape — leftover marinade goes straight to burnt sugar under the broiler.
  • A cooling rack over a foil-lined sheet catches drips and keeps the underside from steaming.
  • No butterfish at your market? Salmon or a firm white fish works, though butterfish's fat content is what makes it iconic.

Keep grinding
