Gelato is an Italian frozen dessert, similar to ice cream. Its ingredients include milk and sugar, often combined with flavorings and fruit, chocolate, liquor, spices, or nuts. Unlike true ice cream, gelato often does not contain cream, and traditionally has a much lower fat content. The term gelato also refers to similar frozen desserts that are prepared in this method. Once combined, the gelato ingredients are cooled; the resulting product contains little air, which results in a denser, more flavorful dessert. A form of gelato made with water and no milk or soy milk is called sorbetto. Gelato is best served fresh. Northern Italy is famous for the dairy form of gelato, and Southern Italy and Sicily take credit for the sorbetto version.
