What Is Dulse?

Palmaria palmata, or dulse, is a red seaweed that grows wild in the cold waters of the Northwest Pacific Ocean and the North Atlantic Ocean. An edible seaweed with shades ranging from red to dark purple, dulse is characterized by its unique color and the way it grows on the face of rocks and boulders. The first recorded use of seaweeds in North America was in the early 1600s when it was offered to scurvy-ridden European sailors by the native Indians of the East Coast of Canada. Writings from approximately 600 AD tell of St. Columba and the monks of Iona eating it.

Dulse is painstakingly harvested by hand during a short summer season of June to October. Once debris (such as shells) is removed and dried in the sun, it is ready to be flaked, powdered, and shipped. Otherwise, it is simply packed and shipped.

It is commonly used as a:

  • cooking ingredient,
  • snack,
  • body scrub,
  • and medicinal treat.

The best dulse comes from Atlantic Canada and is sought after by gourmands and alternative health followers worldwide.

Dulse flakes can be used in baking.

Tips for Eating Dulse

Dulse can be eaten on its own or used to cook or bake a dish. It comes in a variety of states, making a versatile ingredient in your kitchen.

  • Fresh Dulse
  • Dehydrated Dulse: This can be stored easily for several months.
  • Dulse Flakes
  • Powdered Dulse: Try adding a teaspoon to a smoothie or sprinkling it over bread or pizza dough prior to baking. Stir it into teas or as an ingredient in medicinal tinctures.
  • Dulse Capsules: These are commonly found in health food stores and from alternative medicine practitioners.

Dulse tastes salty and can be sprinkled over salads, cooked potatoes, or on chowders to add flavor.

Bacon, Lettuce, and Dulse (BLD) Sandwich

Use dulse as a bacon substitute to create a healthy twist on an old favourite: the BLT, or bacon, lettuce, and tomato sandwich!

What You'll Need:

  • 2 slices whole-grain/multi-grain bread
  • Butter/organic mayonnaise
  • Tomato slices

  • Handful dulse

  2. Spread a little butter or organic mayonnaise lightly over the toast.
  3. Layer tomato slices and dark leaf lettuce onto the toast.

  5. Sprinkle the dulse with freshly ground black pepper, and your sandwich is done!

Serve the sandwich with a tall glass of organic milk, soy milk, or almond milk for a well-rounded meal. Enjoy a small piece of dark chocolate for dessert to celebrate your good health choices!

Use caution if you choose to pick dulse from areas near towns, cities, and industries. Dangerous waste and chemicals could be present as contaminants.

Daniel and his brothers from the story in the Bible, were taken into the Babylonian captivity and refused to eat the rich and decadent diet of the court. Daniel and his companions chose rather to eat vegetables and dulse. Having a more simple and healthy diet enabled them to keep their wits about them in a strange and godless culture. ~ Book of the Prophet Daniel ~ from the Torah

Hi AliciaC - yes, dulse has a salty flavour. I have heard of people sprinkling the flakes on french fries and scrambled eggs too. Thanks for stopping by!

I enjoyed reading your hub. The nutrient list was very useful. I sprinkle dulse and kelp granules and flakes on food instead of salt. They add a nice flavor and I like their nutritional benefits.

Middlespecialist - I hadn't heard of dulse either until I read about it in a book about Canadian organic farmers. Glad you enjoyed the hub - I really enjoyed researching it!

Thanks for the comment, RTalloni. Dulse is one of the lesser known seaweeds in North America, but is slowly gaining in popularity.

Middlespecialist on March 18, 2011:
