Dulse, or Palmaria palmata, is a type of edible seaweed with an impressive nutrition profile. It’s rich in macro- and micronutrients, including protein, fiber and antioxidants.

It’s also called dillisk, dilsk, red dulse, sea lettuce flakes and creathnach.

It grows wild on the northern coasts of the Atlantic and Pacific Oceans and is harvested at the beginning of summer and fall seasons.

Dulse looks like a leafy, red lettuce when it’s fresh, although it’s hard to find the seaweed fresh because it’s usually dried immediately after harvest. When the seaweed is raw, it has a leathery texture, and the fonds, which grow from the root, vary in shape.

You can find dried, packaged dulse products in some grocery stores. It’s available in whole-leaf and flaked forms and can be purchased as a powder or in seasoning mix.

Along with its notable antioxidant and nutrient content, dulse is well-loved for its taste, which has been likened to that of bacon.
