If you're a fan of Japanese flavors, you'll love this Kanpachi teriyaki recipe. To make this dish, you will need Kanpachi fillets, soy sauce, mirin, sake, sugar, garlic, ginger, and green onions. Start by making the teriyaki sauce. In a small saucepan, combine soy sauce, mirin, sake, sugar, garlic, and ginger. Bring the mixture to a boil, then reduce the heat and simmer for about 5 minutes, or until the sauce thickens slightly. Set the sauce aside. Season the Kanpachi fillets with salt and pepper, then heat some oil in a skillet over medium-high heat. Add the fish and cook for about 3-4 minutes on each side, or until the fish is cooked through. Once the fish is cooked, pour the teriyaki sauce over it and let it simmer for a minute or two, until the sauce coats the fish. Serve the Kanpachi teriyaki with steamed rice and garnish with sliced green onions. The sweet and savory flavors of the teriyaki sauce complement the delicate taste of the Kanpachi perfectly.
