Produced from a plum, this red seasoning is made from the juices created by the pickling of ume plums. Tart and salty in flavor, ume plum vinegar is used as both a seasoning and an ingredient for beverages, salad dressings, steamed vegetables, rice dishes, dips, sauces, and food spreads. The ume plum is a Japanese fruit used most often as a condiment, which is referred to as umeboshi plums. However, the ume plum vinegar and umeboshi vinegar are different in flavor and ingredients. The umeboshi vinegar has more of the brine or pickled flavor, resulting in a saltier-tasting vinegar. As a substitute for ume plum vinegar, use red-wine vinegar.
