To roll your sushi wraps: Place the nori sheet shiny side down (you can use a piece of parchment paper to help with rolling if you wish). Spread a generous ¾ cup of rice in an even layer over the nori, leaving a few centimetres uncovered at the top. In a thin, even layer, top the rice with your desired fillings. Run a damp finger across the top edge of the nori to help seal it after rolling. Grasp the end of the nori roll and begin to roll it tightly into a log. Seal the long edge of the log with a little more water. Slice in half widthwise, and enjoy!
