Gelato, or the plural Gelati, is ITALIAN ice cream made from a liquid, milk or water; a solid, sugar, fats or sweeteners; flavorings, pastes, fruit powders; stabilizers, guar gum, locust bean, etc.; emulsifiers, mono- and digylcerides; and air.
The process in which gelato is made varies on the ingredients used as it can be made using a hot process, which includes pasteurization or as a cold process which doesn't require pasteurization. Both processes require a gelato batch freezer, which makes the end product by mixing the ingredients and incorporating air. Like high-end ice cream, gelato generally has less than 55% air, resulting in a denser and more flavorful product.
