*If you use a metal cocktail shaker, place it in the freezer to chill it or shake some ice cubes in it for a few seconds. This is done to ensure that the metal will contract and form a tight seal for when we do a "dry shake" (shaking without ice) with the ingredients. If you attempt to do a dry shake in a metal cocktail shaker without first chilling it, it's gonna leak everywhere.
