Laver is a type of SEAWEED that is commonly used in Japanese cuisine. It is also known as Nori and is usually dried and cut into thin strips. It is often used to wrap sushi rolls or as a garnish for other dishes. The term 'laver' comes from the Welsh word for SEAWEED, which is 'llawr'. The ROD is a tool used to harvest laver from the sea. It is a long pole with a net attached to the end, which is used to scoop up the SEAWEED from the ocean floor.
