Raisins are dried grapes. They are small, sweet, and chewy, and are often used as a snack or as a topping or ingredient in a variety of dishes. They are made by drying grapes in the sun or in a dehydrator until the moisture content is reduced to about 15%. The grapes can be any variety, but they are typically dark-colored grapes such as Thompson seedless, Flame seedless, or Black Corinth. Raisins are a good source of antioxidants, fiber, and iron, and they are also low in calories. They can be eaten on their own or used in a variety of recipes, such as baked goods, cereals, granola bars, and trail mix.
