Overview: The seaweed known as dulse, otherwise known as Neptune’s girdle, is a rosy-bladed red algae that is widely distributed in the Atlantic & Mediterranean Oceans. Dulse has purple-red, short-stemmed, fan-shaped fronds that grow in tidal areas on rocks, shells, and larger algae. Dulse is rich in vitamins and minerals including iodine and can be eaten raw, roasted, boiled, fried, or dried as a relish. The custom of eating dulse, an acquired taste, dates back to at least 600 A.D. in northern Europe. Dulse used as a medicine is said to have a tonic effect and was traditionally used to treat scurvy and constipation. It is often added to soups, salads, and chowders in coastal towns where it can naturally be found.
