What is Miso Paste?

Miso paste is made by combining cooked soybeans with salt and a starter culture called koji, which is a type of mold that grows on rice or barley. 

The mixture is then fermented for months or even years in wooden barrels or ceramic pots. 

The result is a thick, smooth paste that ranges in color from white to dark brown, depending on the type and duration of fermentation

The longer the fermentation, the darker and saltier the miso paste becomes.
