Full of delicious sea flavour, these crisp sheets are made from seaweed that is processed into very thin, flat sheets. Roasted Seaweed Sushi Sheets (Nori) can be enjoyed on their own as a delicious salty snack with cold sake or Japanese beer. They are most frequently used in the preparation of Nigiri sushi and Hand Rolls and can also be finely shredded as a garnish on dishes.
