A milkshake is a sweet, cold beverage which is made from milk, ice cream or iced milk, and sweet flavorings such as fruit syrup or chocolate sauce in Canada, most regions of the United States, Australia, and the United Kingdom. Milkshakes are usually served in a tall glass with a straw, and whipped cream may be added as a topping. Four popular milkshake flavors are vanilla, chocolate, strawberry, and the black and white, made using vanilla ice cream and chocolate syrup.Full-service restaurants, soda fountains, and diners usually prepare and mix the shake "by hand" from scoops of actual ice cream and milk in a blender or drink mixer using a stainless steel cup. Fast food outlets do not use actual ice cream, but manufacture their shakes in milkshake machines which freeze and serve a premade milkshake mixture. Throughout the United States, especially in fast food and casual dining restaurants, a milkshake may be referred to as a shake.
