First Step: Prepare the Marinade
In a bowl, whisk together 1 tablespoon soy sauce, 3 tablespoons mirin, 1 tablespoon sake, 1 teaspoon grated fresh ginger (optional but recommended), and, if using, 1 tablespoon honey or sugar until well combined. This mixture forms the flavorful base that tenderizes and infuses the salmon.

Second Step: Marinate the Salmon
Place the salmon fillets in a ziplock bag or shallow dish. Pour the marinade over the salmon, ensuring the fillets are evenly coated. Remove excess air from the bag, seal, and refrigerate for at least 3 hours, preferably overnight. Long marination allows the flavors to deeply penetrate the fish for maximum taste.

Third Step: Preheat the Grill
Preheat your grill to medium-high heat (approx. 400°F / 200°C). Oil the grill grates lightly to prevent sticking. For indoor cooking, a broiler set to high or a grill pan can be used.

Fourth Step: Grill the Salmon
Remove the salmon from the marinade, letting any excess drip off. Place the fillets skin-side down on the grill. Cook for 4-5 minutes without moving to achieve a crispy skin. Flip carefully, baste with reserved marinade, and grill for another 3-4 minutes. Cooking times vary based on thickness; look for opaque flesh and a slight pink center.

Final Step: Rest and Serve
Transfer salmon to a plate and let rest for a few minutes to allow juices to redistribute. Garnish with toasted sesame seeds and sliced green onions if desired. Serve with steamed vegetables, rice, or simply fresh greens for a balanced meal. This dish adapts well to dietary needs by swapping soy sauce with tamari for gluten-free or substituting salmon with tofu for vegan versions.
