Gelato is the common word in Italian for all kinds of ice cream. In English, it specifically refers to a frozen dessert of Italian origin. Artisanal gelato in Italy generally contains 6–9% butterfat, which is lower than other styles of frozen dessert. Gelato typically contains 35% air and more flavoring than other kinds of frozen desserts, giving it a density and richness that distinguishes it from other ice creams.

Ice cream is a frozen dessert typically made from milk or cream that has been flavoured with a sweetener, either sugar or an alternative, and a spice, such as cocoa or vanilla, or with fruit, such as strawberries or peaches. Food colouring is sometimes added in addition to stabilizers. The mixture is cooled below the freezing point of water and stirred to incorporate air spaces and prevent detectable ice crystals from forming. It can also be made by whisking a flavoured cream base and liquid nitrogen together. The result is a smooth, semi-solid foam that is solid at very low temperatures. It becomes more malleable as its temperature increases.
