A sultana is a type of dried grape, specifically made from the Thompson Seedless variety. These grapes are typically light in color and have a sweet flavor, making them a popular choice for snacking and baking. Sultanas are often used in recipes for cakes, cookies, and other desserts, as well as in savory dishes. Sultanas are commonly found in many parts of the world, particularly in Australia, Turkey, and the United States. They are rich in natural sugars, fiber, and various vitamins, making them a nutritious addition to a balanced diet.
