Dulse? Dulse! It's dried seaweed, and the very best dulse comes from Grand Manan Island. When I was a child, it was sold in little packages just like potato chips. Besides being a very tasty treat, it is a natural source of iodine, and prevents goitre.
It is a lovely deep purple colour, crispy, and very, very tasty.
My local supermarkets (here in Fredericton, NB, Canada) sell it, as do the health food stores.
Maybe you have to live here to get it. LOL
