The small, wrinkled fruit often used in cooking is called a raisin. Raisins are dried grapes, and their wrinkled appearance comes from the dehydration process. They can be made from various grape varieties, including both red and white grapes, and possess a concentrated sweetness that enhances many dishes. Commonly used in baking, cooking, and snacks, raisins are popular in recipes such as bread, cookies, salads, and savory dishes. They are also a nutritious snack, packed with natural sugars, fiber, vitamins, and minerals, making them a healthy alternative to candy and other sugary treats.
