Origin Wakayama is the center

Umeboshi is salted and sun-dried ume, a fruit closer to the apricot than the plum, and the sourest, saltiest thing that lands on a Japanese table. Traditionally the fruit is salted with about a fifth of its weight, left to steep in its own brine, and then dried in the midsummer sun. A single umeboshi carries a whole bowl of rice, and that is exactly how it is meant to be dosed.

Background

Facts

Raw material
ume, Prunus mume, harvested yellow and ripe in late May or early June; despite the common name Japanese plum it is botanically closer to the apricot
Method
the fruit is layered with salt, around 20 percent of its weight, steeps for a couple of weeks in the brine the salt draws out, and is then sun-dried on bamboo mats for a few days at the height of summer, a step with its own name, doyoboshi
Salt
a traditional shirahoshi sits around 20 percent salt and above; modern honey and low-salt versions sit at a fraction of that, but then need the preservatives the salt used to be
Color
the red color comes from red shiso added to the brine; without shiso an umeboshi is yellowish brown
Umezu
the leftover brine is called umezu, plum vinegar, though it is no vinegar at all; it is reused in the kitchen and is what gives beni shoga its acidity
Origin
Wakayama is the center, with the towns of Minabe and Tanabe as the largest producers and the cultivar Kishu nanko as the most renowned
History
samurai carried umeboshi as field rations against fatigue, and hinomaru bento, a single red umeboshi in the middle of white rice, is named after the Japanese flag
Confusion
umezuke is the same salted fruit without the sun-drying; it is the drying that makes an umeboshi an umeboshi

At the table

Serving

Dosage
one fruit per bowl of rice or onigiri; umeboshi is one bite at a time, never a portion
Serving
in the middle of an onigiri, on the rice in a bento, mashed into chazuke, or as acidity in dressings and stews; for colds, traditionally in rice porridge
Note
a properly salted umeboshi keeps for years in the pantry; the low-salt versions belong in the fridge and carry a date for a reason
