Umeboshi are pickledume fruits common in Japan. The word umeboshi is often translated into English as 'salted Japanese plums', 'Japanese plums' or 'preserved plums'. Ume is a species of fruit-bearing tree in the genus Prunus, which is often called a "plum", but is actually more closely related to the apricot. Pickled ume which are not dried are also called umezuke. Umeboshi are a popular kind of Japanese tsukemono and are extremely sour and salty. Sweet umeboshi made with honey also exist. They are usually served as a side dish for rice or eaten on rice balls for breakfast and lunch. They are occasionally served boiled or seasoned for dinner.
Physical characteristics
Umeboshi are usually round, and vary from smooth to very wrinkled. Usually they taste salty, and are extremely sour due to high citric acid content, but sweeter versions exist as well. Umeboshi were notorious for their ability to eat their way through the plain drawn aluminum lunch boxes commonly used in the 1960s. The combination of organic acids and salt in the umeboshi were the cause of this phenomenon. The central area of Wakayama prefecture is known throughout Japan for the number and quality of its ume and umeboshi. The town of Minabe, Wakayama, in particular, grows more ume and produces more umeboshi than any other town in Japan.
Production
Umeboshi are traditionally made by harvesting ume fruit when they ripen around June and packing them in barrels with 20% salt per weight of fruit. The salt extracts juice, which the ume then soak in for about two weeks. This salty, sour liquid is marketed as umezu Many varieties of umeboshi sold on the market are desalinated to a certain extent and re-soaked in a flavoring liquid. They are sometimes dyed red using purple perilla herbs, or flavoured with katsuobushi, kombu or even sweetened with honey. Because these flavored varieties end up at 3% to 15% salt content, they usually contain a natural or artificial preservative to extend shelf life. Natural preservatives include vinegar, alcohol, and vitamin B1.
Consumption
Umeboshi are usually eaten in small quantities with rice, for added flavor. It is also a common ingredient in onigiri, rice balls wrapped with nori, and they may also be used in makizushi. Makizushi made with umeboshi may be made with either pitted umeboshi or umeboshi paste, often in conjunction with slivered fresh green perilla leaves. The standard Japanese folk remedy for colds and flus is okayu with umeboshi. Another usage of umeboshi is in "Ume chazuke", a dish of rice with poured in green tea topped with umeboshi. Umeboshi were esteemed by the samurai to combat battle fatigue, a function of their salt and citric acid content, among other factors. Salt, citric acid, and polyphenols also contribute to their antimicrobial activity, so they are a natural preservative for foods and help prevent food poisoning and other bacterial stomach problems. Umeboshi is used as a cooking accent to enhance flavor and presentation. They may also be served as a complement of a drink with shochu and hot water. Umeboshi are often eaten as snacks; in the United States and Australia, many Japanese grocery stores stock them. Eating umeboshi in Japan is the equivalent of the English expression "an apple a day". Children's candy shops sometimes carry karikari ume, or prepackaged, crunchy pickled ume, and dried umeboshi.
Health
This Japanese style traditional condiment is believed to be a digestive aid, prevention of nausea, and for systemic toxicity, including hangovers. Green ume extract is used as a tonic in Japan. The citric acid is believed to act as an antibacterial, help to increase saliva production and assist in the digestion of rice. Additionally, umeboshi is claimed to combat fatigue and protect against aging.

The umeboshi style of pickling is common in Japan and is similar in style to other Asian preserved pickling techniques found in China, Vietnam, and Korea. In Vietnam, a very similar variety of pickled ume is called xí muội or ô mai. In South Asian countries, Indian gooseberries called amla in Hindi or Amala in Nepali is prepared in similar way, sometimes with sugar syrup. In Mexico, it is known as chamoy and is usually made with apricot, ume or tamarind and a mix of salt and dry chili. In South Africa, a similar style of preserved dried fruit is called mebos in Afrikaans, the name of which seems to derive from the Japanese via Dutch trade. Usually, apricot is used to produce a salty, acidic variety, although other, sweetened varieties made from other fruits are also colloquially called mebos.
