What is the primary culinary function of Kombu when creating dashi?

Answer

Making dashi, the savory broth stock that forms the backbone of many dishes

Kombu is identified as the most foundational seaweed variety because it is essential for preparing dashi. Dashi is the savory broth stock that serves as the foundational flavor base for countless Japanese soups and sauces. Often, the Kombu itself is simmered down to extract this primary umami flavor, meaning it contributes profoundly to the meal's profile even though it might become invisible by the time the final dish is presented, functioning much like salt or commercial stock cubes do in other cuisines.
