Dulse
The bacon of the sea — the red frond every forager falls for first.
By Jayson Byles, forager & chef · Updated August 2026
Dulse (Palmaria palmata) is the best-loved red seaweed of the North Atlantic — soft, hand-shaped fronds of deep red-purple on the lower shore, prized for a salty-sweet, smoky depth that has earned it the nickname the bacon of the sea. In old Ireland a rock with dulse on it was said to be worth more than two cows; on the East Neuk shore it is simply the frond we reach for first — and, dried, the backbone of our seaweed salt.
How do you identify dulse?
Look for flat, soft blades that divide into rounded finger-like lobes — a shape like a loose glove — in deep red through purple, growing on rock and very often directly on the stipes of kelp. Blades run to 30 cm or so, with a texture more supple than the crisp reds around it. It holds the lower shore, so a good spring low is your invitation. The one name-based confusion — pepper dulse — is settled instantly by size and taste: pepper dulse is tiny, tough and hot.
Where and when to find it
Lower shore rock and kelp stipes, from July onward — but the connoisseur’s season is September to November, when the blades darken and the flavour peaks. Cut fronds above their base and leave the holdfast; dulse regrows generously when harvested with manners.
How do you cook dulse?
Three doors in: fry it briefly in a dry or lightly-oiled pan until it crisps — the bacon moment, transformative beside eggs; flake it dried over potatoes, soups, doughs and even brownies as a seasoning that out-works salt; or eat it as is — dried dulse is a chewy, moreish snack straight from the jar, and slow drying coaxes out its natural sugars. It carries iron, calcium and iodine with vitamins A through D, which is a fine excuse for the brownies. It seasons our seaweed muffins, and a pinch lifts a dram at a whisky tasting.
