Dulse is a red algae that thrives in the cool coastal waters of the Atlantic and the Pacific. It is also called lobe kelp, dulce or oil. The algae leaves have a reddish brown colour, grow up to 20cm long and can be harvested all year round. Dulse powder is a great addition in the kitchen: it is wonderful as an additive in soups, salads, smoothies or in baking mixes. It is also often used as a salt substitute. The algae are already very popular, especially in countries like Ireland, France or Sweden. They are dried at a gentle temperature and then ground into a fine powder. The taste is slightly nutty. Dulse is a natural source of iodine.
