Hideki Hiwatashi's salmon futomaki recipe is a great sushi to try if you're new to this art form. Futomaki translates to 'fat rolls', an apt name for this chunky form of maki. It's easiest to work out the quantities of filling ingredients by sight, as you'll need to trim them to the size of your nori sheets.
