About umeboshi Edit
Umeboshi are pickled Japanese plums that are picked before they're ripe, then soaked in brine and red Shiso leaves, the latter of which adds flavor and a pink coloring. This Japanese condiment is very salty and tart and is a popular adjunct to most Japanese meals, including breakfast. Pureed umeboshi, called bainiku, is used as a seasoning. Umeboshi can be found in jars and cans in Asian markets and in some gourmet markets.
