Raisins are dried grapes that are typically small, sweet, and chewy. They can be made from a variety of grapes, but are most commonly made from seedless grapes such as Thompson Seedless. Raisins are often used in cooking and baking, and are a popular snack food as well. They are also a good source of fiber, vitamins, and minerals, including iron and potassium. Raisins can be eaten on their own or added to dishes such as oatmeal, salads, trail mix, and baked goods.
