Where It Grows
Kombu Kelp is a type of seaweed that grows in cold, clear waters, primarily in the coastal areas of East Asia, specifically Japan, Korea, and China. It thrives at depths of about 5 to 20 meters, particularly in areas where the current is strong. Due to its preference for colder waters, it is mostly harvested in the fall and winter months. The major kombu producing regions are Hokkaido and Iwate in Japan, which is known for having some of the highest quality kombu kelp in the world.
Best Way to Eat
Kombu Kelp is often consumed in a variety of ways, but the most common and nutritionally beneficial is to use it as a base for soups and broths. This not only imparts a rich, umami flavor to the dishes but also allows for the extraction of its nutrients into the liquid. It can also be eaten raw, or dried and then rehydrated for use in cooking. To maximize its nutritional value, kombu should not be overly boiled or cooked for extended periods, as this can reduce its iodine and mineral content. Additionally, adding a splash of vinegar or a squeeze of citrus to kombu can help to break down its fibrous structure and make its nutrients more bioavailable.
