Long valued for its medicinal properties, the East Asian stone fruit ume appears in Japan’s oldest pharmacological dictionary, written in 918. Something between a plum an apricot, the ume is more acidic than both and rich in antioxidants. The first mention of umeshu, a liqueur made by steeping ume in usually distilled spirits and commonly translated as plum wine, came centuries later in a book of Japanese cuisine published in 1697. Ume’s medicinal value appears to have carried over, though, as this later work claims that the flavorful tonic both spurs the appetite and counteracts poisons.
