A cocktail shaker is large cup-like mixing tool used to mix beverages by shaking ice with drink ingredients. The shaking causes a rapid cooling of the liquid ingredients.
A shaken cocktail is made by putting the desired ingredients (typically fruit juices, syrups, liqueurs and ice cubes) in the cocktail shaker. Then it is shaken vigorously for 5-8 seconds. Drinks that are meant to be clear should be stirred and not shaken, as this will result in the drink becoming cloudy.
There are three varieties of cocktail shakers:
A) The Boston Shaker: A two-piece shaker consisting of a metal bottom and glass or plastic mixing bowl. A separate strainer is required for this type shaker if crushed ice is used.
B) The French Shaker: A two-piece shaker consisting of a metal bottom and a metal cap. It is the least widely known of the three types of shakers. A strainer is always required for this type of shaker.
C) The Cobbler Shaker: A three-piece cocktail shaker that has tapers at the top and ends with a built-in strainer and includes a cap. The cap can often be used as a measure for spirits or other liquids.
