What is the purpose of a jigger?

A jigger is a two-sided measuring tool used in bartending to pour precise amounts of liquor. It typically features one side that measures a standard shot (1.5 ounces) and a smaller side that measures a half-shot (0.75 ounces). The importance of the jigger lies in its ability to ensure consistency in cocktail preparation, which is vital for maintaining the intended flavor profile and alcohol content of drinks.

Using a jigger allows bartenders to adhere to recipes accurately and provide customers with a reliable drinking experience. This precision not only helps in achieving the correct balance of ingredients for optimal taste but also aids in responsible serving by controlling the amount of alcohol being poured.

The other choices do not align with the primary function of a jigger. While stirring, shaking, and chilling cocktails are essential aspects of mixology, they involve different techniques and tools, such as stirring spoons, shakers, and ice, rather than measuring liquids. Therefore, the use of a jigger specifically relates to the accurate measurement and pouring of liquor.
