If you're cooking rice from scratch, remember that 1 cup of uncooked rice will yield around 3 cups of cooked rice. We use six cups of cooked rice in this recipe (2 cups of uncooked rice) which should leave you with approximately 12 sushi rolls. We like to allow 2-3 rolls per person if you're serving them as a light dinner without sides. Cook more rice if you'll be serving more people.
