You can make all kinds of sushi without seaweed, but you need a grinder to make the rice balls into various shapes, which is available on Taobao. I've also had salmon sushi at a sushi restaurant, where the salmon is laid directly on top of the rice ball, again without seaweed. Sushi rice cooking method determines the sushi will not be scattered, the best edible rice + glutinous rice to 10:1 ratio mix, you can cook a soft and sticky sushi rice, the amount of water for a cup of rice to a cup of water; if more than five cups of rice, reduce the last cup of water 1 / 5 amount of water, so that the rice made into a ball after the pressure is not easy to scatter.
