Irish Moss harvesting in PEI, Canada, compliments of North Atlantic Organics
Irish Moss has been used as mattress stuffing, cattle feed, and in printing. It was most famously used as ‘poverty food’ by the Irish in the 19th century, especially during the Irish Potato Famine of 1846-1848.
Having been driven to consume Irish Moss in large amounts, for long periods of time, the Irish remained averse to the seaweed for a long time after this period. Today, Irish Moss is enjoying a strong revival everywhere, especially in Ireland and was noted as the most searched term on Pinterest in 2019!
According to ancient Irish folklore, Irish Moss was carried on trips for protection and safety, and placed beneath rugs to increase luck and to ensure a steady flow of money into the house or pockets of the household. Irish Moss was also used widely in the treatment of tuberculosis and pneumonia. In Ireland and parts of Scotland, it was boiled in milk and strained, before sugar and other flavourings such as vanilla, cinnamon, brandy or whiskey were added. The end-product is a kind of jelly similar to panna cotta. In Venezuela it has been used for generations as a home remedy for sore throats and chest congestions, boiled in milk and served with honey before bed.
The Irish Moss industry provides a unique way of life for those involved with the harvest on Prince Edward Island (Canada). The industry began with a small number of fishermen in the 1930s and quickly grew into a multimillion-dollar industry in just a few decades. This was largely due to the demand for the carrageenan that was extracted from the harvested moss. In its heyday, entire communities were involved in the collection of the saltwater plant, Irish moss along the shores of PEI. Today, the industry is still alive but to a lesser extent, and primarily only in the western part of the province. The methods of harvesting using horse-drawn rakes to gather the windswept moss were developed on PEI and can be seen to this day along the west coast. Most of the harvesting is now done by boat but there are still those who gather moss along the shoreline after a storm.
Irish Moss is used as a source of industrial carrageen for various industries, where it is used as a thickener and stabilizer. To a lesser extent, it is used for fining beer or wine as a clarifying agent. In the recent years, the raw food movement has made extensive use of the whole plant to produce a thick gel that gives texture to raw cakes and for many other food applications.
