Raisins are naturally sweet, dried grapes that are enjoyed worldwide as a healthy snack and versatile ingredient. They are produced by dehydrating ripe grapes, either in the sun or using controlled mechanical drying methods, which concentrates their natural sugars and nutrients. Raisins have a wrinkled texture, a chewy consistency, and a rich, fruity flavor. They are available in various types such as golden, black, and green, depending on the grape variety and drying process.
