Ice cream is a frozen dessert that can be made using cream or a combination of cream and custard base. Flavorings or fruits are often added before freezing. It is commonly made by churning the mixture in a machine, but it can also be made in ice-cube trays. Hand-churning produces the smoothest texture, while battery and electric-operated machines also produce good results. Special recipes and steps are needed when making ice cream in ice-cube trays.
