We had this dish on our trip to Hawaii and have worked to recreate it ever since. The fish takes some forethought and prep, but the cooking time is quick and easy.
- 1/4 cup sake
- 1/4 cup mirin
- 1/4 cup white miso paste
- 3 tablespoons white sugar
- 4 cod fillets
- 1 tablespoon sesame oil
- 1 tablespoon green onions for garnish
- At least two days BEFORE you plan to eat this dish, make the miso marinade. Bring the sake and mirin to a boil in a medium saucepan over high heat. Boil for 20 seconds to evaporate the alcohol.
- Turn the heat down to low, add the miso paste, and whisk. When the miso has dissolved completely, turn the heat up to high again and add the sugar, whisk to ensure that the sugar doesn't burn. Remove from heat once the sugar is fully dissolved. Cool.
- Pat the black cod fillets thoroughly dry with paper towels. We usually use frozen, slightly defrosted filets for this since fresh cod is hard to come by here. Add the fish and the marinade to a sealable Tupperware container. Leave to marinate in the refrigerator for 2 to 3 days. We suggest lightly flipping the container when you open the refrigerator during those two days.
- Preheat oven to 400°F. Heat an oven-proof skillet, such as a cast-iron skillet, over high heat on the stovetop. Lightly wipe off any excess miso clinging to the fillets, but leave some on (just not big clumps).
- Add a bit of sesame oil to the pan, then place the fish in the pan and cook until the bottom of the fish browns and blackens in spots, about 3 minutes. Flip and continue cooking until the other side is browned, 2 to 3 minutes. Transfer to the oven and bake for 5 to 10 minutes, until fish is opaque and flakes easily.
