Cool and empty the shaker as well. For home use we recommend the 'cobbler shaker', also called traditional or continental.
It consists of three parts: a lower part (made of steel, glass or plastic), which acts as a container where the ingredients are placed, a first upper part consisting of a perforated cap that serves as a filter, also called a dome, and a second upper part which represents the lid, also called the hat, to be placed over the filter.
The three parts must be perfectly interlocked in order to avoid any unwanted leaks during shaking.
The cocktail is poured simply by opening the lid, the strainer action is ensured by the special dome which removes the need to use a separate strainer.
