Badderlocks, also called winged kelp or dabberlocks, is an edible brown seaweed made from Alaria esculenta, a cool-water kelp that grows on wave-exposed Atlantic rocks in Ireland, Scotland, Iceland and Scandinavia. Long, olive-brown and split by a prominent central midrib, it is the North Atlantic's answer to Japanese wakame — sweet, tender and gently marine when the young fronds are cooked or dried.
