what is jigger

The term "jigger" has two different meanings. One meaning refers to a small parasitic flea that burrows into the skin of a warm-blooded host before laying eggs. The other meaning refers to a common bar essential that acts as a cocktail measuring cup. Jiggers are dual-sided and help bartenders cut down on overpouring and remain consistent when crafting cocktails. They have different capacities on each end and range from 0.5 to 2.5 ounces. There are several different sizes of jiggers, and you should always double-check jigger measurements when following a cocktail recipe.
