Creating Miso Glazed Black Cod is a simple yet rewarding process. Follow these steps for an incredible result:

1. Prepare the Marinade: In a medium bowl, whisk together the white miso paste, sake, mirin, maple syrup, and soy sauce until smooth.
2. Marinate the Fish: Place the black cod fillets in a shallow dish or resealable bag. Pour the marinade over the fish, ensuring each piece is evenly coated. Cover and refrigerate for 4-6 hours or overnight for deeper flavor.
3. Preheat the Oven or Grill: Preheat your oven to 400°F (200°C) or prepare a grill for medium-high heat.
4. Remove Excess Marinade: Take the fish out of the marinade and gently wipe off the excess. This helps in preventing burning during cooking.
5. Cook the Fish:
– For Baking: Place the fillets on a lightly greased baking sheet. Bake for 15-20 minutes or until the fish is cooked through and flakes easily with a fork.
– For Grilling: Brush the grill grates with vegetable oil. Grill the fillets for about 3-5 minutes on each side, ensuring they get nice grill marks and are cooked through.
6. Rest the Fish: Once cooked, let the fish rest for a few minutes. This allows the flavors to settle.
7. Garnish: Serve the black cod garnished with thinly sliced scallions and toasted sesame seeds for an appealing look and added flavor.
8. Enjoy: Plate the Miso Glazed Black Cod with your choice of sides and enjoy!
