Sobre este ingrediente
Premium kombu variety from the waters around Rishiri and Rebun islands in northern Hokkaido. Distinguished by clarity and depth of dashi (less sweet than ma-kombu, more refined than hidaka). Traditionally the kombu of choice for Kyoto kaiseki cuisine and ceremonial-grade dashi. Production is allocation-constrained — annual harvest is closely controlled by local fisheries cooperatives. Used in premium dashi, soup base, and kombu extract for cosmetic moisturisation lines.
