Kanpachi teriyaki is a delicious and flavorful way to enjoy amberjack. To make this dish, you will need kanpachi fillets, soy sauce, mirin, sake, sugar, and vegetable oil. Start by marinating the kanpachi fillets in a mixture of soy sauce, mirin, sake, and sugar for at least 30 minutes. Heat vegetable oil in a pan and sear the marinated kanpachi fillets until they are golden brown on both sides. Once the fillets are cooked, remove them from the pan and set aside. In the same pan, add the remaining marinade and cook until it thickens into a glaze. Pour the glaze over the kanpachi fillets and serve with steamed rice and vegetables. The teriyaki glaze adds a sweet and savory flavor to the tender kanpachi, making it a crowd-pleasing dish that is perfect for any occasion.
