Laver is an edible seaweed that is often used in various dishes. It is also known as gim in Korea and nori in Japan, although these terms are sometimes used interchangeably to describe different types of seaweed. Laver is a type of red algae that grows near the high-water mark of the intertidal zone in both the Northern and Southern hemispheres. It is harvested, dried, and used as food in greater amounts than any other seaweed, giving it significant economic importance. Laver is considered to be a nutritious seaweed with high levels of iodine, iron, and protein. It also contains vitamins and minerals like vitamin A and vitamin B2. Laver is often eaten wrapped around rice, as a garnish on soups, and as a snack on tables when drinking beer in Korea. In Wales, it is sometimes grilled on toast and is reported to have an oyster-like taste. Laver is also commonly eaten with bacon.
