Laverbread (//) is a food product, made from 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 east coast of Ireland along the Irish Sea, where it is known as slake. It is smooth in texture and forms delicate, sheetlike thalli, often clinging to rocks. The principal variety is Porphyra umbilicalis. Porphyra (laver seaweed) is classified as red algae; it 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 since at least the 17th century. It is prepared by washing repeatedly and then boiled until it becomes a soft mush when it is known as laverbread. The gelatinous paste that results can then be sold as it is, or rolled in oatmeal; it is sometimes coated with oatmeal prior to frying. Laverbread is traditionally eaten fried with bacon and cockles as part of a Welsh breakfast, or with hog's pudding in the south west of England.
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. It is plucked from the rocks and given a preliminary rinse in clear water. The collected laver seaweed is repeatedly washed to remove sand and boiled for hours until it becomes a stiff, green mush. In this state, the seaweed can be preserved for about a week. Typically during the 18th century, the mush was packed into a crock and sold as "potted laver".
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.
Laverbread can be eaten cold as a salad with lamb or mutton. A simple preparation is to heat the laverbread and to add butter and the juice of a lemon or Seville orange. Laverbread can be heated and served with boiled bacon.
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 slake. It is smooth in texture and forms delicate, sheetlike thalli, often clinging to rocks. Porphyra is classified as red algae; it tends to be a brownish colour, but boils down to a dark green pulp when prepared. It is unusual amongst seaweeds because the fronds are only one cell thick. 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.
Laverbread (Welsh: bara lafwr or bara lawr) is a traditional Welsh delicacy made from laver seaweed. To make laverbread, the seaweed is boiled for several hours, then minced or pureed. The gelatinous paste that results can then be sold as it is, or rolled in oatmeal; it is sometimes coated with oatmeal prior to frying.
Laverbread is traditionally eaten fried with bacon and cockles as part of a Welsh breakfast. It can also be used to make a sauce to accompany lamb, crab, monkfish, etc., and to make laver soup (cawl lafwr). Richard Burton has been quoted as describing laverbread as "Welshman's caviar".
Laver seaweed is often associated with Penclawdd and its cockles, being used traditionally in the Welsh diet and is still eaten widely across Wales in the form of laverbread. In addition to Wales, laverbread is eaten across the Bristol Channel in North Devon, especially the Exmoor coast around Lynmouth, Combe Martin and Ilfracombe. In North Devon it is generally not cooked with oatmeal and is simply referred to as 'laver' (lay-ver).
