When a drink contains eggs, fruit juices or cream, it is necessary to shake the ingredients. Shaking is the method by which you use a cocktail (or "Boston") shaker to mix ingredients together and chill them simultaneously. The object is to almost freeze the drink whilst breaking down and combining the ingredients. Normally this is done with ice cubes three-quarters of the way full. When you have poured in the ingredients, hold the shaker in both hands, with one hand on top and one supporting the base, and give a short, sharp, snappy shake. It is important not to rock your cocktail to sleep. When water has begun to condense on the surface of the shaker, the cocktail should be sufficiently chilled and ready to be strained.
Never use makeshift shakers - two glasses, one upside down over the other, is an extremely bad idea - the rims of the glasses break and drop glass shards into the mix (not to mention they leak).
