What is miso butter?

Miso butter is a compound butter made by combining miso paste and unsalted butter. Miso paste is a fermented soybean paste that is common in Japanese cuisine. The mixture creates a rich, umami flavor that can be used in a variety of dishes. Miso butter is often used as a spread for bread and crackers, but it can also be used to add depth to sauces, marinades, and roasted vegetables. This butter is easy to make at home by combining equal parts of miso paste and softened butter, and mixing until it forms a smooth consistency. Miso butter can be stored in the refrigerator for several weeks.
