Kelp

Kelp.jpg

Kelp can be used in soups and stews, stir-fried with vegetables, or cooked with beans or grains.

Kelp plants can grow to a length of nearly 200 feet (about 61 meters), making this the largest variety of sea vegetable. It is light brown to dark green in colour and is similar to kombu, although it is thinner and more tender. It is found chiefly on the Atlantic and Pacific Coasts of North America.

Varieties

The predominantly available variety of kelp is the giant kelp (Macrocystis pyrifera).

Buying and storing tips

Dehydrated kelp should be stored in an airtight container in a dark, dry place. Cooked kelp should be kept under refrigeration.

Availability

Kelp is sold dehydrated, and in flake and powder forms for use as a condiment.

Preparation, uses, and tips

Like kombu, kelp is used in soups and stews, stir-fried with vegetables, or cooked with beans or grains. It cooks quickly and dissolves in longer-cooking dishes. It contains a natural glutamic acid, a tenderizer that helps beans cook quickly and makes them more digestible. It also contains alginic acid, a substance used as a thickening and stabilizing agent in food production. Kelp can be pre-soaked or added dry to foods with liquids. Kelp absorbs up to five times its weight in liquid.
