Toro is the fatty meat of tuna served as sushi or sashimi. It is usually cut from the belly or outer layers of the Pacific bluefin tuna. The etymology of the name comes from the fact that the meat has a creamy texture. According to the Sushi: The Complete Guide by Masuo Yosino, a customer at the Yoshino Sushi Honten named it as toro melts in your mouth.
