Laverbread ('leiv@r-,_'la:v@r-; bara lafwr or bara lawr; sleabhac) is a food product made from laver, an edible seaweed (littoral alga) consumed mainly in Wales as part of local traditional cuisine. The seaweed is commonly found around the west coast of Great Britain, and the coasts of Ireland, where it is known as sleabhac. It is smooth in texture and forms delicate, sheetlike thalli, often clinging to rocks. The principal variety is Porphyra umbilicalis, a red algae which tends to be a brownish colour, but boils down to a dark green pulp when prepared. Laver seaweed has a high content of dietary minerals, particularly iodine and iron. The high iodine content gives the seaweed a distinctive flavour in common with olives and oysters. Laver seaweed has been cultivated as a food in Wales since at least the 17th century. It is prepared by repeated washings and then boiling until it becomes the soft purée-like product known as laverbread. The gelatinous paste that results can then be sold as it is or rolled in oatmeal. It is sometimes also coated with oatmeal prior to frying. Laverbread is traditionally eaten fried with bacon and cockles as part of a Welsh breakfast or, in the southwest of England, with hog's pudding. Porphyra umbilicalis Laverbread is made from the seaweed Porphyra umbilicalis from the genus Porphyra and family Bangiaceae. The seaweed is commonly found around the west coast of Great Britain and east coast of Ireland along the Irish Sea, where it is also known as sleabhac or slake. Laver has a high content of dietary minerals, particularly iodine and iron. The high iodine content gives the seaweed a distinctive flavour in common with olives and oysters. Cultivation of laver seaweed as food is thought to be very ancient, though the first mention was in William Camden's Britannia in the early 17th century. Laver seaweed cultivation is typically associated with Wales, and it is still gathered off the Pembrokeshire and Carmarthenshire coasts, although similar farming methods are used at the west coast of Scotland.

Seaweed

Seaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. The term includes some types of Rhodophyta (red), Phaeophyta (brown) and Chlorophyta (green) macroalgae. Seaweed species such as kelps provide essential nursery habitat for fisheries and other marine species and thus protect food sources; other species, such as planktonic algae, play a vital role in capturing carbon, producing at least 50% of Earth's oxygen. Natural seaweed ecosystems are sometimes under threat from human activity.

Porphyra

Porphyra (du grec porphyra, « pourpre ») est un genre d'algues rouges de la famille des Bangiaceae, comprenant environ 70 espèces. Elle vit sur l'estran, typiquement entre la zone intertidale supérieure et l'étage supralittoral des mers froides et tempérées, notamment près des laisses de haute mer où elle est capable de supporter de longues émersions. En Asie du Sud-Est, elle est utilisée comme varech pour produire le nori (au Japon) et le (en Corée). Elle y est aussi cultivée et transformée pour être consommée directement pour l'alimentation humaine.

Vitamine B12

La , également appelée cobalamine, est une vitamine hydrosoluble essentielle au fonctionnement normal du cerveau (elle participe à la synthèse des neurotransmetteurs), du système nerveux (elle est indispensable au maintien de l'intégrité du système nerveux et tout particulièrement de la gaine de myéline qui protège les nerfs et optimise leur fonctionnement) et à la formation du sang. C'est l'une des huit vitamines B.
