Japan Region / Locale: Tokyo Servings: 4 servingsGunkanmaki, or ‘battleship roll’, is a type of sushi from Japan. Characterized by its boat-like shape, it features a nori seaweed wrapper filled with vinegared rice and topped with a variety of delicate ingredients like fish roe, sea urchin, or chopped scallop. Originating in the 1940s in Ginza, Tokyo, this sushi was developed to serve soft, loose toppings that other sushi forms could not retain. Its unique shape allows for luxurious and diverse fillings, making it a staple in sushi bars and an inviting culinary canvas for innovative toppings.
