Dried seaweed, also known as nori in Japanese or laver in English, is an edible seaweed that undergoes drying for preservation. It typically appears as thin, dark green to black sheets, semi-transparent and slightly glossy. Its texture is crisp and delicate, akin to thin paper, becoming brittle when toasted. Dried seaweed boasts a distinctive umami flavor, savory with a hint of saltiness, varying in intensity based on type and processing.
