Sultanas are dried grapes that are typically lighter in color and sweeter than raisins. They are made from white or green grapes, and are often treated with sulfur dioxide to preserve their pale color. Sultanas are plump and juicy, and are commonly used in baked goods, cereals, and snack mixes. They are a good source of antioxidants and fiber, and are also low in calories. Like raisins, sultanas can be eaten on their own as a snack or used in a variety of recipes
