However, if California rolls all the fancy sushi you see, there is usually a fancy name, or fire-baked sushi, such as sushi, but foie gras or salmon is put on it and baked with a fire gun, then the heat will be very high, because these two kinds of sushi usually contain mayonnaise with high heat, and the former will also contain high-heat materials such as cheese, bacon and foie gras. Because California rolls are invented by Americans, I personally understand that sushi is necessary.
