Raisins are processed by sun drying and tray drying several different types of grapes. They are small and sweetly flavored with a wrinkled texture. Indian Raisins are available in different size and colors. They have a flavor similar to the grapes from which they are made, but the drying process which creates them concentrates the amount of sugar making them taste much sweeter. They are a naturally stable food and resist spoilage due to their low moisture.
