Soy and barley miso is a type of miso (a fermented soybean paste) that is made from soybeans and barley. It has a dark brown colour and a strong, savoury flavour, and is often used in Japanese cooking to add flavour and aroma to dishes, such as soups, marinades and sauces. Soy and barley miso is generally stronger in flavour than other types of miso, and is often used to add a robust, umami flavour to dishes.
