Salmon fillets marinated in a sweet white miso, mirin, sake, and cane sugar glaze, then broiled until caramelized and flaky. A copycat of the Nobu miso recipe.
Make the Marinade: In a pot, boil the mirin and sake for 3 minutes. Add the cane sugar and miso and cook a few more minutes without boiling. Cool completely.
Marinate the Salmon: Pour a little of the cooled marinade into the bottom of a non-reactive dish. Place the salmon skin side down and pour the rest of the marinade over the top. Move the pieces around so every side is fully coated, then flip them skin side up. Cover tightly with plastic wrap and refrigerate at least 24 hours, up to 2-3 days.
Prepare the Fish: Let your salmon get to room temperature for about 15-20 minutes.
Broil: Preheat the broiler for about 5-10 minutes on high (550°F). Line a baking sheet with aluminum foil and place the marinated salmon on top with space in between. Broil about 5 inches away from the heating element for about 7 minutes (adjust for thickness), until the salmon is opaque and flakes easily. Check the thickest part with an instant-read thermometer: 135°F (57°C) for medium-rare or 145°F (63°C) for well done. If the top is getting too dark, you can move it down to finish cooking.
This recipe also works on the grill or in a pan. See the Ways to Cook Miso Salmon section for more info.
Optional: Add the remaining marinade to a saucepan and boil for at least 5 minutes, stirring frequently. Brush over the cooked salmon before serving.
