What is miso?

Miso is a condiment produced by fermenting soybeans, rice or wheat together with salt and koji culture. Sometimes soybeans are called the ‘meat of the field’ because of the high amount of protein. Fermented soybeans contain a variety of amino acids and vitamins, making it healthy when consumed in moderation. Loaded with other nutrients and fibers, miso helps the body maintain the balance and contributes to a daily diet of Japanese people.

There are many types of miso, classified by the main ingredient (rice, barley or soybean miso) or color due to the manufacturing method (red, white miso).
