Sour cherry, also known as tart cherry or Montmorency cherry, is a type of cherry that is prized for its tart flavor and nutritional benefits. Unlike sweet cherries, which are commonly eaten fresh, sour cherries are usually used for cooking, baking, or making juice. They have a distinct bright red color and are smaller in size than sweet cherries. Sour cherries are native to Europe and Asia but are now widely cultivated in many parts of the world, including the United States, Canada, and Australia. They have been used for centuries in traditional medicine for their anti-inflammatory and antioxidant properties. Today, sour cherries are enjoyed not only for their flavor but also for their potential health benefits.
