Kanpachi teriyaki is a delicious and savory dish that combines the flavors of soy sauce, mirin, and ginger with the tender kanpachi fillets. To make kanpachi teriyaki, you will need kanpachi fillets, soy sauce, mirin, sugar, grated ginger, vegetable oil, and sesame seeds for garnish. Start by making the teriyaki sauce by combining soy sauce, mirin, sugar, and grated ginger in a small saucepan. Heat the saucepan over medium heat and simmer until the sauce thickens slightly. In the meantime, heat vegetable oil in a skillet over medium-high heat. Add the kanpachi fillets to the skillet and cook for about 2-3 minutes per side, or until the fish is cooked through. Pour the teriyaki sauce over the cooked kanpachi fillets and let them simmer in the sauce for a minute or two to absorb the flavors. Serve the kanpachi teriyaki over steamed rice and garnish with sesame seeds for added texture and flavor.
