Gelato originated in Sicily, Italy, where it was originally made from snow and ice brought down from mountaintops. In 1686, the first ice cream machine was invented by Sicilian fisherman Francesco Procopio dei Coltelli, increasing gelato's popularity. Gelato is a frozen dessert made from milk, cream, sugars, and flavorings like fruit or nuts. It has lower calories, fat, and sugar than ice cream. Gelato must contain at least 3.5% butterfat in Italy. The gelato mixture is prepared using a hot process to dissolve sugars before freezing and serving at a warmer temperature than ice cream.
