Sour cherries, also known as tart cherries, are small, bright red fruits that pack a tangy punch. Unlike their sweet counterparts, these cherries have a sharp flavor that makes them perfect for cooking and baking. They are often used in pies, jams, and sauces, adding a delightful tartness that balances sweetness in desserts. These cherries are not just tasty; they are also packed with nutrients. Rich in vitamins A and C, as well as antioxidants, sour cherries can help boost your immune system. Many people enjoy them fresh, but they are also commonly found dried or frozen, making them a versatile ingredient year-round.
