On the plate

Briny and direct raw, it turns nutty and sweet as soon as it dries.

Avoid: Gathering it on a rock exposed to harbour or outfall water: it concentrates everything.

The nori sheet as we know it was invented around 1750, when Asakusa papermakers applied the washi paper technique to the alga, spreading it on bamboo screens.
