Jack in the Box Wiki


A milkshake (sometimes simply called a shake) is a sweet drink made by blending milk, ice cream, and flavorings or sweeteners such as butterscotch, caramel sauce, chocolate syrup, fruit syrup, or whole fruit into a thick, sweet, cold mixture. It may also be made using a base made from non-dairy products, including plant milks such as almond milk, coconut milk, or soy milk. Shakes have been sold at Jack in the Box since the 1950s.

Milkshakes originated in the United States around the turn of the 20th century, and grew in popularity following the introduction of electric blenders in the subsequent two decades. They became a common part of youth popular culture, as ice cream shops were a culturally acceptable meeting place for youth, and milkshakes became symbolic of the innocence of youth.

Full-service restaurants, ice cream shops, soda fountains, and diners usually prepare the shake in a specialized mixer known as a milkshake machine. At home, a blender is more commonly used. Milkshakes may be made from any flavor of ice cream; additional flavorings, such as chocolate syrup, malt syrup, or malted milk powder, are often added prior to mixing.

Many fast food outlets do not make shakes from the individual ingredients; rather, they use automatic milkshake machines which freeze and serve a pre-made milkshake mixture consisting of milk, a sweetened flavoring agent, and a thickening agent. These are similar to soft-serve ice cream machines, but keep the shake at a drinkable consistency.
