White miso, also known as "shiro miso" in Japanese, is a type of fermented soybean paste that has a white or pale yellow color and a mild and delicate flavor. It is made from cooked soybeans, rice or barley, salt, and white koji, a fermenting fungus that gives it its characteristic color and flavor.

White miso is typically fermented for a shorter period than other types of miso, which gives it a milder and lighter flavor. It is often used to season soups, sauces, marinades, and dressings, as well as for dips and sweet dishes.
