Umeboshi paste, made from salted and pureed plums, is widely used in Japanese cuisine. It is characterized by its strong sour taste, saltiness, and unique flavor. This combination adds a refreshing touch to dishes and stimulates the appetite.

Umeboshi paste is used in various Japanese dishes. For example, it is often served with chilled tofu (hiyayakko), and is popular as a dip for yakitori and tempura. Additionally, incorporating umeboshi paste into chicken or pork rolls creates a delightful balance between the meat's umami and the paste's sourness. Furthermore, it is used as a filling for onigiri (rice balls) and as a dressing for sunomono (vinegared dishes).

During the hot summer months, umeboshi paste's refreshing taste is especially valued, making it an easy-to-eat option even when appetite is low. As a result, many households and restaurants offer dishes featuring umeboshi paste, making it a beloved ingredient year-round.
