Spiral Foods Yaki Sushi Nori is a garnish or flavouring in noodle preparations and soups. It is most typically toasted before consumption (yaki-nori). A common secondary product is a toasted and flavoured nori (ajitsuke-nori), in which a flavouring mixture (variable, but typically soy sauce, sugar, sake, mirin and seasonings) is applied in combination with the toasting process.
