Umeboshi are pickled ume, sour Japanese fruits somewhere between plums and apricots. Umeboshi are often eaten for breakfast, or as a pickle-like side-dish with boxed lunches. They’re a common filling for onigiri (rice balls), a lunch staple. Umeboshi can be grated and mixed with soy sauce for dressing chicken or salad. They are considered highly medicinal, used for hangovers, digestive ailments and to “purify” the blood. Many older Japanese people eat one every morning, for energy, the same way samuris did hundreds of years ago.

These look delish. Anyone know where to get them?
