Ume Plum Vinegar (umeboshi vinegar)

A liquid byproduct of umeboshi plum production; green plums are pickled with salt water and red shiso leaves for approximately one year yielding marooncolored salty sour plums and a pinkish liquid with a similar flavor. Umeboshi vinegar is delicious in dressings soups and sauces but be careful a little goes a long way!
