Muso From Japan Organic umami puree is a natural umami rich seasoning. This Ginger and chili, aka "shout koi", koi infused with ginger or chili then aged with traditionally brewed soy sauce. Used as an alternative to salt/soy sauce for any type of cooking and pickling. It makes an excellent natural tenderizer for fish and meat. Overall it reduces the need for salt while enhancing umami flavor!
