Grilled kohada is a simple yet delicious way to enjoy the flavors of gizzard shad. To make grilled kohada, you will need the following ingredients: fresh kohada fillets, soy sauce, mirin, sake, sugar, and grated ginger. Start by marinating the kohada fillets in a mixture of soy sauce, mirin, sake, sugar, and grated ginger for at least 30 minutes. Preheat your grill to medium-high heat. Place the marinated kohada fillets on the grill and cook for about 3-4 minutes on each side, or until the fish is cooked through and slightly charred. Serve the grilled kohada with steamed rice and a side of pickled vegetables for a complete meal. The grilling process enhances the natural flavors of the kohada, resulting in a smoky and savory dish that is sure to impress your taste buds.
