Ingredients: - 4 Hamachi fillets - 1/4 cup soy sauce - 2 tablespoons mirin - 2 tablespoons sake - 2 tablespoons brown sugar - 1 tablespoon grated ginger - 2 cloves garlic, minced - 1 tablespoon vegetable oil Steps: 1. In a small bowl, whisk together the soy sauce, mirin, sake, brown sugar, ginger, and garlic. 2. Place the Hamachi fillets in a shallow dish and pour the teriyaki marinade over them. Let them marinate for 30 minutes. 3. Heat the vegetable oil in a large skillet over medium-high heat. 4. Remove the fillets from the marinade and place them in the skillet. Cook for 3-4 minutes per side, or until the fish is opaque and flakes easily with a fork. 5. While the fish is cooking, pour the marinade into a small saucepan and bring it to a boil. Reduce the heat and simmer for 5 minutes, or until the sauce has thickened slightly. 6. Serve the Hamachi teriyaki with the thickened sauce drizzled over the top. Enjoy!
