Using Dried Kombu in Cooking

Dried kombu, a type of seaweed commonly used in Japanese cuisine, is a versatile ingredient that can add depth and umami flavor to a variety of dishes. Made from the dried kelp of the Laminaria japonica sea vegetable, kombu is rich in glutamates, which are naturally occurring amino acids that give foods their savory, meaty flavors.

Preparing Dried Kombu for Use​

Rehydrating and Shredding Kombu​

Before using dried kombu in cooking, it's essential to rehydrate the seaweed by soaking it in water. This process not only makes the kombu easier to shred but also brings out its full flavor potential. To rehydrate dried kombu, simply place it in a bowl or container and cover it with cold water. Allow the kombu to soak for at least 30 minutes to an hour before removing it from the water and shredding it into fine strips.

Using Kombu in Soups and Stews​

One of the most popular ways to use dried kombu is by adding it to soups and stews. The seaweed's rich umami flavor pairs well with a variety of ingredients, including vegetables, meat, and fish. To use kombu in soup or stew, add the shredded seaweed towards the end of cooking time, allowing its flavors to meld with the other ingredients.

Making Kombu Broth​

Another way to use dried kombu is by making a flavorful broth. To make kombu broth, combine shredded kombu with water and simmer for 10-15 minutes. Strain the mixture through a fine-mesh sieve to remove any solids, then season with salt and other desired flavorings.

Seasoning With Kombu Powder​

For added convenience, dried kombu can be powdered using a spice grinder or food processor. Kombu powder can be used as a seasoning in a variety of dishes, from soups and stews to salads and stir-fries. When using kombu powder, start with small amounts and taste as you go, as the flavor of the seaweed can quickly become overpowering.

Tips for Using Dried Kombu​

  • To prevent the flavor of dried kombu from becoming too strong, use it in moderation.
  • Rehydrate dried kombu before using it to bring out its full flavor potential.
  • Experiment with different seasoning combinations when using kombu powder to find your favorite flavors.
