Pisco Sour | Cocktail

This is how the Pisco Sour cocktail is prepared:

To prepare, put the ingredients in a shaker with ice and pour the mixture into a cocktail glass. Tip: Adding a dash of Angostura or about a quarter of egg white may enhance the taste experience. Sometimes a pinch of cinnamon is also added. To make the cocktail a bit more refreshing, more ice cubes can be added after pouring into the glass.', 'The Pisco Sour is the Chilean national drink. Originally (and in the original recipe) the cocktail was mixed with lime juice, however the juice of lemons is also good. For the preparation is best suited the Gran Pisco of Control (this provides the best, smoothest taste).
