Seasoned Ma-Kombu from southern Hokkaido, pine-cut and simmered by Japan's foremost kelp house since 1871. One pinch. Deep, rounded umami.
Shio kombu is kelp simmered in soy sauce and seasonings until concentrated, then dried. A scatter of strips over warm rice, folded into butter, or dropped into a finishing sauce — and the dish changes.
This version is made by Okuikaiseido, established in 1871 in Tsuruga, Fukui. For over 150 years the company has sourced, aged, and processed kombu from Hokkaido for professional kitchens across Japan. Award-winning chefs from around the world have visited the Okuikaiseido warehouse to see the aging cellars firsthand. The company is the Gift-in-Kind sponsor of the Culinary Institute of America.
The kelp is Ma-Kombu, harvested from Shiraguchihama in southern Hokkaido — the origin of Japan's most refined and aromatic kombu. Ma-Kombu carries a naturally sweet, clean glutamate profile and holds through cooking without turning sharp or bitter.
After simmering in soy sauce, the strips are cut matsuba style — narrow and forked like pine needles — then slow-dried. The outside sets dry and firm; the inside stays tender. The result is concentrated, gently sweet, savory, and firm enough to hold its shape on a plate.
A pinch of shio kombu replaces finishing salt and adds umami in a single step. No preparation is needed. It begins releasing flavor the moment it meets a warm ingredient or sauce.
