Irish Moss
Irish Moss is an edible North Atlantic seaweed that yields a mucilaginous substance. It is found on the Atlantic coasts of Ireland, Europe and the United States. Irish Moss got its name when it was made famous during the potato famine in Ireland in the 1800s. Because people were starving and desperate for food, they began eating the red alga that was on the rocks. As a result, the name stuck. This alga is also referred to as carrageen moss because of its high carrageen content. Carrageen is a common food additive used to maintain stability within processed foods and as a thickening agent.
