It is also a rich source of protein and B vitamins. At low tide, the arching stems of the rich brown Kombu plants hover above the water’s edge, the flat shiny blades immersing themselves in the swirling currents. Each blade is trimmed 5–8 cm above the stipe to ensure. the continued growth of Kombu, and then individually hung to be sun-dried in the redwood hills. Indispensable in soups and beans also makes tasty pickles and nutritious condiments.
