About

A milkshake is a sweet, cold beverage which is made from milk, ice cream or iced milk, and flavorings or sweeteners such as fruit syrup or chocolate sauce.

Full-service restaurants, soda fountains, and diners usually prepare and mix the shake "by hand" from scoops of ice cream and milk in a blender or drink mixer. Most fast food outlets do not make shakes by hand with ice cream. Instead, they make shakes in automatic milkshake machines which freeze and serve a premade milkshake mixture.

Some fast-food restaurants serve milkshakes which are prepared by blending soft-serve ice cream (or ice milk) with sweetened, flavored syrups such as chocolate syrup and fruit-flavored syrup and milk.
