Dulse
Palmaria palmata
Along the cold shores of Ireland, Scotland, and Iceland, dulse has been gathered from the rocks at low tide for well over a thousand years, dried in the wind, and carried inland as a treasured trade good. Coastal families ate it plain as a chewy, salty snack, simmered it into soups and broths, and leaned on it through lean winters when fresh greens were scarce. Its iodine content made it a folk remedy for swollen throats and sluggish vitality long before anyone understood the thyroid, and sailors on long voyages chewed dried dulse to guard against scurvy. In Icelandic sagas it appears as söl, valued enough to be counted as part of a laborer's wages.

Traditional preparations.
A simple coastal preparation traditionally sipped to help replenish minerals and support the thyroid, thanks to dulse's natural iodine content.
Simmer 1 tablespoon of dried dulse flakes in 250 ml of water for 5 to 10 minutes, then strain and sip warm.
A traditional Irish and Scottish coastal snack, eaten plain or crumbled over food for a savory, mineral-rich bite.
Toast a small handful of dried dulse fronds in a dry skillet over low heat for about a minute, until crisp, then eat as is.
Safety.
Dulse is naturally high in iodine, so those with thyroid conditions or on thyroid medication should watch their intake. As with any seaweed, source it from a reputable, tested supplier.
