1. To clean the kombu, wipe it with a damp cloth. If you wsh it, some of the flavor will go away. Since bonito is not being added to this recipe, you want the full flavor of the kombu. 2. Soak kombu in the water for 1 hour. 3. After the 1 hour soak, bring water to a boil, removing the kombu just before the water starts boiling. ---------------------------------------------------------------------------
