This is the lean cut of the tuna. It was quickly cured in soy sauce before being pressed onto the bed of rice. I find the color of this sashimi so attractive, a brilliant, luminous, wine-red color. I love the way this sushi was prepared. The time the fish spends marinating in the soy sauce highlights and elevates the natural umami of the tuna. It had a fantastic firm, meaty bite that paired well with the soft grains of perfectly seasoned rice.
