Boston shaker

  1. A cocktail shaker consisting of two parts: a metal tin, typically 28 oz in size, and a 16-oz pint glass. After adding the ingredients to one half of the Boston shaker, the other half is inserted and the drink can be shaken. Unlike the cobbler shaker, a Boston shaker usually necessitates the use of a separate strainer to strain the drink into its serving glass, though the drink may also be strained by creating a small gap between the tin and glass that is too narrow for ice to pass through.
