Laver

Laver is a type of edible red seaweed, commonly found along the coastlines of the British Isles and other temperate regions. It is typically harvested from the wild and then cleaned, dried, and often toasted or fried to create a crisp texture and concentrated flavour.

Laver is used as a flavouring ingredient, particularly in savoury snacks and dishes, where it imparts a distinct umami taste and a slightly salty, oceanic profile. It is frequently found in seaweed snacks, crisps, and as a seasoning for rice or noodle dishes.

Laver is not a food additive and does not have an E-number. It is a source of various minerals, including iodine, and vitamins. As with many seaweeds, the iodine content can be high, and excessive intake could potentially affect thyroid function, though typical consumption levels in food are unlikely to cause issues. The Food Standards Agency (FSA) provides general advice on consuming seaweed, particularly regarding iodine content.
