A sweet-savory Kyoto miso infused with Tamba-grown sansho pepper — citrusy, gently tingly, and built to glaze, marinate, or finish with depth.
Sansho Miso is a condiment-style miso from the Tamba region of inland Kyoto Prefecture where sansho has long been part of the local culinary tradition. The sansho used here comes from Ayabe, a farming community in northern Kyoto, where sansho berries develop their sharp citrus aroma and the clean, mouth-tingling sensation that makes sansho unlike any other pepper.
The base is Obata Miso, a rice miso made from Koshihikari rice grown in the mountain fields of Tamba, fermented to develop its characteristic sweetness and depth. Sweet by design, mirin builds the body while sugar rounds the edges. What sets this apart is the use of mi-zansho: whole sansho berries, not ground powder or extract. Used whole and unground, the berries carry their full citrus-pepper character directly into the miso base.
Ayako, Umami Curator at The House of Umami, visited Waira Tamba’s office and lab in Tamba, Kyoto and tasted through the range. Two things decided it. The sansho miso itself: whole mi-zansho berries worked into a sweet base, with an aroma more layered and expressive than anything she had tasted made with ground sansho. And the people behind it: a two-generation family operation, parent and child, working the same craft with quiet dedication. Both mattered.
While sansho is most often used as a finishing condiment, this miso holds up equally well through heat. Brush it on salmon before sliding it under the broiler. Stir it into pan drippings with a small knob of butter for a fish or pork pan sauce. Fold it into compound butter for tableside finishing. Thin it with dashi and reduce slightly for a glaze with enough depth to anchor an entire plate.
