Sea Vegetables refer to an amazing renewable resource whose potential has often been overlooked. It has been used as fertiliser and food by coastal dwellers for hundreds of years. Traditionally its main use was as fertiliser, spectacularly documented in the film “The Field”, referred to in that famous quote from Bull McCabe, “God made the world and seaweed made that field”. As depicted in the film many poor costal areas with little or no soil cover relied completely on the long term spreading of seaweed mixed with sand to build up a sufficiently deep layer of soil for cultivation. During Ireland’s disastrous potato famine of 1847-48 seaweed was used commonly as a food and led to negative associations of seaweed with poverty and famine. This hard shaken image has gradually changed in Ireland as people awoke to the realisation that seaweeds were not a poor man’s alternative but rather are superior to many land based vegetables as a source of minerals, trace elements and vitamins.
