Who founded miso?
Miso’s origins can be traced back to the 4th century bc in china, in the form of a soybean paste called jiang—a fermented food that was originally made with animal protein instead of plant-based protein. Jiang began to spread out of china and into adjoining countries around the 7th century bc. It is thought that miso originated as a fermented food in ancient china. It is most likely that it was introduced to japan via mainland china and the korean peninsula in the asuka period during the 7th century. The characters for miso first appeared in literature during the heian period.
