Hotate – Raw Scallop – Scallop sushi is the softest sushi in the shellfish category. The sweetness of the scallop is easily tasted due to its high glycogen content. The muscle that connects the organs to the shell is used for the main sushi ingredient. Other parts of the body are not used. Scallops have big cylindrical connector (or adductor) muscles since they can jump and swim near the ocean floor
