What is a Nori?

Nori is a type of edible seaweed most commonly used in Japanese cuisine, particularly in sushi rolls. It is made from various species of red algae, including Porphyra, and is commonly cultivated in coastal waters. Once harvested, it is dried and pressed into thin sheets, giving it its characteristic dark green or black appearance.

Nori has a slightly salty and savory (umami) taste, with delicate crispy textures when dried and roasted. It is incredibly versatile for culinary use—it can be eaten as-is, crumbled over dishes, or used as a wrap for rice and other fillings. Nori sheets pair especially well with soy sauce and sesame oil.

This seaweed is rich in nutrients, including iodine, an essential mineral for thyroid health, and vitamin B12, which supports nerve function and energy metabolism. It also contains small amounts of proteins, fiber, and antioxidants while being very low in calories.
