Fermenting soybeans with koji creates savoury miso paste

Salt and microorganisms transform soybean mash into a complex fermented condiment

Miso is a traditional Japanese paste produced by fermenting soybeans with salt and koji cultured rice or barley. The fermentation process can last from several weeks to a few years, depending on the desired colour and strength. Fungal and bacterial activity converts soybean proteins into umami-rich amino acids, yielding white, red, or dark brown miso.
