Profile

Ribbon Kelp (Alaria marginata)

Ribbon kelp features long, narrow blades with undulating edges and a thick spine known as a "midrib", visually similar to the midrib of leafy land vegetables like kale or chard. It can grow up to 13 feet tall and, as an annual species, it grows and dies in the span of a single season. When ready to reproduce, it sprouts short, fluttering, spore-releasing blades at its base. Ribbon kelp thrives on rocky shores in the mid to low intertidal zone from Alaska to central California in a variety of habitats, from exposed to semi-protected.

For generations, ribbon kelp has been integral to the traditional lifeways of Pacific Northwest indigenous cultures. Beyond its practical uses for food and medicine, ribbon kelp has been woven into the myths and spiritual practices of Alaskan tribes since time immemorial, symbolizing connections between humans, the supernatural, land, and sea. For indigenous people of Alaska, farming ribbon kelp has become a way to reclaim native knowledge that has been appropriated over the centuries.

Texture

Light and feathery

Preparation Tips

The blades and midrib of ribbon kelp have distinct textures, densities and cook times so it's best to separate them as you would a kale leaf from its stem. Use kitchen shears to cut the blades along both sides of the midrib before storing or cooking. To soften the fibrous texture of the midrib, simmer for 10-20 minutes.
