Umeboshi

What Is Umeboshi?

Umeboshi is a traditional Japanese pickle made by fermenting unripe Japanese plums (Prunus mume, ume) in a large amount of salt for weeks and then drying them in the sun. It is usually fermented together with red shiso (perilla) leaves; this leaf gives it both its deep red color and its aroma.

Its taste is extremely sour and salty; it is rarely eaten raw in large pieces, and is more often used in small amounts as a complementary ingredient. Its pitted, mashed form (umeboshi paste) is used in sauces and marinades.

Nutritional Values of Umeboshi

Being fruit-based, umeboshi is low in calories (about 30 kcal per 100 grams), but due to the traditional salting method, its sodium content is very high. Values can vary greatly by brand and salting ratio; they are approximate.

How Should Umeboshi Be Consumed?

Due to its very high salt content, umeboshi is consumed in small amounts, usually together with rice or other foods; eating a large amount on its own is not recommended.

This information is general; umeboshi is a food, not a substitute for medical treatment. Since its sodium content is very high, careful and moderate consumption is recommended for those on salt restriction.

How to Choose Umeboshi?

A good umeboshi has skin that is wrinkled but whole, a color that is dark red-pinkish (if fermented with shiso), and a sharp-sour smell. Ones that appear overly hardened or moldy should not be preferred.

• Skin should be wrinkled but whole, not crushed/broken
• Smell should be sharp-sour and pleasant
• Salt ratio should be checked on the label (traditional ones are usually very salty)

How to Store Umeboshi?

Umeboshi can be kept for a long time in the fridge in a sealed jar, in its own brine; its high salt ratio acts as a natural preservative and delays spoilage.

Using Umeboshi in the Kitchen

Umeboshi is mostly used as onigiri (rice ball) filling, alongside hot rice, and in umeboshi paste form in salad dressings or marinades; it's considered a sour-salty balancing element in Japanese cuisine.

Why Is Umeboshi So Sour and Salty?

Unripe plums naturally contain high citric acid; in traditional production, fermenting for a long time with heavy salt and drying in the sun both provides preservation and creates the characteristic sharp taste-saltiness.
