Kiri-Dashi Konbu/Kombu
Dr. Kikuni Ikeda set out early in the 20th century to identify the subtle deliciousness of kombu (kelp). Until then, it had been thought that the receptors on our tongues detected only sweet, sour, salt and bitter. Dr. Ikeda discovered that we also had receptors for glutamates the source of the savoury yumminess of kombu and many other foods and he called it umami.
