Where It Grows

Nori Sheets are made from a species of red algae, most commonly Porphyra yezoensis and Porphyra tenera. This type of seaweed naturally grows in the intertidal zones of cold water coastal areas. It is cultivated in a variety of regions globally, with the highest production rates in East Asian countries such as Japan, China, and South Korea. The cultivation process typically involves seeding nets with Nori spores and submerging these nets in the sea, where they are harvested after a period of growth. Optimal conditions for growth include cool water temperatures and a high level of sunlight for photosynthesis.

Best Way to Eat

Nori sheets are commonly used in sushi preparation, where they are wrapped around a rice and fish or vegetable filling. They can also be toasted lightly and used as a garnish in a variety of dishes, or shredded and mixed into salads. For a nutrient-rich snack, they can be eaten straight from the pack, or lightly toasted and seasoned with a sprinkle of sea salt. Nori is high in iodine, vitamin A, and vitamin C, so consuming it raw or lightly toasted can help to maximize these nutrients. Flavour can be enhanced through toasting, which brings out a savory, umami taste.
