...Nori seaweed is a type of ocean vegetable and is sold in thin, easy to tear sheets. These sheets are dark green, shiny and translucent when held up to the light. The flavor is vegetal and ocean-like with a hint of salt. Toasted nori has a rounder flavor. Nori is used in the making of sushi and is also commonly sold as a snack in smaller sheets that may be flavored with sesame, soy or some kind of seasoning.
