Popular Types Of Japanese Seaweed

Due to the fact that it’s an island, most of Japan’s cuisine is highly tied to the sea, giving us the rich and unique flavors and textures that we’ve come to associate with Japanese cooking.  But it’s not just the fish or rice that everyone thinks about when they think Japanese food, it’s also the seaweed (a very important element of the Japanese diet for centuries) that plays an vital role in the authenticity and taste of the cooking.

What is Japanese Seaweed Used For?

Japanese seaweed (called Kaiso) comes in many different varieties and is cultivated directly from the ocean.  Today, you can purchase Kaiso from almost any market specializing in Japanese cuisine, but it used to be that one would either have to go out and get it themselves.  While the role of Japanese seaweed has dwindled in modern cuisine, it is still heavily used in certain dishes, especially as soup stocks, seasoning and sushi dishes.
