Umeshiso is a traditional Japanese condiment made from umeboshi (pickled ume fruit) and shiso leaves. It typically has a tangy, salty flavor and is used to enhance various dishes, including rice, salads, and grilled meats. The combination of ume and shiso not only adds a unique taste but also provides health benefits, as both ingredients are rich in antioxidants and nutrients. Umeshiso can be enjoyed as a dip, spread, or seasoning.
