How to roll sushi?
Use a sushi mat. It depends what kind of sushi you want to make, but for the regular kind, you’d place the seaweed down on the mat and layer everything else; roll the entire business using the mat from underneath. Inside-out sushi is a little more complex, but pretty much the same idea. What you’ll do is put the seaweed down first and the rice second; then using the mat, flip over and begin to layer.
