Shaken coffee is prepared by placing ice cubes (about 6), liquid sugar and coffee in a shaker: close the shaker and shake vigorously for a few seconds and pour into a glass (possibly already iced).
There are many variations and additions to this recipe, as each person (or barman) prepares it according to their own tastes and adds their own "secret" ingredient. When preparing shaken coffee, it is important to use liquid sugar, because granulated sugar may not dissolve completely due to the cold.
