Slice the maguro into thin pieces and place each slice on top of a rice ball. Press the fish gently to adhere it to the rice. Serve the maguro nigiri sushi with soy sauce, wasabi, and pickled ginger on the side. Dip each sushi piece into the soy sauce and add a small amount of wasabi and pickled ginger for extra flavor. Maguro nigiri sushi is a classic and elegant dish that showcases the natural flavors of the tuna. The combination of the tender fish and the slightly tangy sushi rice creates a delightful bite-sized treat.
