Umeboshi

What Is Umeboshi?

Umeboshi is a traditional Japanese pickle made by fermenting unripe Japanese plums (Prunus mume, ume) with plenty of salt for weeks and then drying them in the sun. It is often fermented with red shiso (perilla) leaves, which give it both its deep red color and aroma.

It is extremely sour and salty; it is rarely eaten raw in large pieces and is more often used in small amounts as an accompaniment. Pitted and mashed umeboshi (umeboshi paste) is used in sauces and marinades.

Umeboshi Nutrition Facts

Because umeboshi is fruit-based, it is low in calories (about 30 kcal per 100 g), but its traditional salting method makes it very high in sodium. Values can vary widely by brand and salting level; they are approximate.

How to Eat Umeboshi

Because umeboshi is very high in salt, it is eaten in small amounts, usually with rice or other foods; eating a large amount on its own is not recommended.

This is general information; umeboshi is a food and is not a substitute for medical treatment. Because it is very high in sodium, people who need to limit salt are advised to consume it carefully and in moderation.

How to Choose Umeboshi

Good umeboshi is wrinkled but intact, dark red to pinkish in color (if fermented with shiso), and has a sharp, sour smell. Avoid pieces that look excessively hardened or moldy.

• The skin should be wrinkled but intact, not crushed or broken
• It should have a sharp, sour, pleasant smell
• Check the salt content on the label (traditional varieties are generally very salty)

How to Store Umeboshi

Umeboshi can be stored in its own brine in a sealed jar in the refrigerator for a long time; its high salt content acts as a natural preservative and delays spoilage.

Using Umeboshi in the Kitchen

Umeboshi is commonly used as a filling for onigiri (rice balls), served with hot rice, or mashed into a paste for salad dressings and marinades; it is considered a sour and salty balancing element in Japanese cuisine.

Why Is Umeboshi So Sour and Salty?

Unripe plums naturally contain high levels of citric acid. In traditional production, fermenting them for a long time in concentrated salt and drying them in the sun both help preserve them and create their characteristic sharp flavor and saltiness.
