How to Eat Kombu Seaweed

By Cynthia Measom

Kombu, a kelp seaweed with a robust flavor, thrives off the coasts of China, Japan and Korea. Because fresh kombu has a short shelf life, this seaweed is most often sold dried. One of this seaweed's most common uses is in a Japanese multipurpose stock, called dashi, which is used to create sauces, soups and stews. You also have other options for eating kombu.

Eating Raw Kombu


Step 1

Rinse the kombu thoroughly under running water. If it is dried, soak it in a container of water for 10 to 15 minutes to rehydrate it.


Step 2

Remove the kombu from the water with a large spoon, and place it on a clean cutting surface. Pour the water into a jar with a lid and refrigerate for up to three days. It can be used as a soup stock.


Step 3

Cut the kombu it into thin, bite-size strips with a knife. Add the desired amount of strips to your favorite salad or use them as a garnish for a soup.
