Irish moss, also referred to as sea moss, is a species of red algae found along the northern Atlantic. Chondrus crispus has a history of traditional herbal use throughout Europe and holds a place within Irish folklore. Nowadays, this “superfood” seaweed is consumed for its vitamin and mineral content. Irish moss naturally contains carrageenan, a substance widely used for its thickening and stabilizing properties. Sprinkle Irish moss on vegetarian dishes, add it to broths, or boil with milk to create a jelly-like dessert dish.
