prunasin

Prunus cerasus (sour cherry, tart cherry or wild cherry) is a species of Prunus in the subgenus Cerasus (cherries), native to much of Europe and southwest Asia. It is closely related to the sweet cherry (Prunus avium), but has a fruit that is more acidic, has greater nutritional benefits, and may have greater medicinal effects. Dried sour cherries are used in cooking including soups, pork dishes, cakes, tarts, and pies. Sour cherries or sour cherry syrup are used in liqueurs and drinks. In Turkey, Greece and Cyprus, sour cherries are especially prized for making spoon sweets by slowly boiling pitted sour cherries and sugar; the syrup thereof is used for vişne şurubu or vyssináda, a beverage made by diluting the syrup with ice-cold water. A particular use of sour cherries is in the production of kriek lambic, a cherry-flavored variety of a naturally fermented beer made in Belgium [Wikipedia].
