Ice cream is a frozen dessert made from dairy products like milk and cream, and often combined with fruits or other flavors and ingredients. It contains sugar and is made by mixing ingredients constantly while freezing to incorporate air and prevent large ice crystals from forming. Common types include ice cream, frozen yogurt, gelato, sorbet, sherbet and ices. Quality ice cream is smoothly textured from small ice crystals formed during rapid, thorough freezing and storage below 0°F. Overrun from incorporated air during churning also affects texture and volume. Popular ice cream desserts include parfaits with layered cream and toppings, and sundaes with scoops of ice cream topped with sauces, fruits and garnishes in
