Pisco Sour

A pisco sour is an alcoholic cocktail of Peruvian origin that is traditional to both Peruvian and Chilean cuisine. The drink's name comes from pisco, a brandy which is its base liquor, and the cocktail term sour, implying sour citrus juice and sweetener components. The Peruvian pisco sour uses Peruvian pisco and adds freshly squeezed lime juice, simple syrup, ice, egg white, and Angostura bitters. The Chilean version is similar, but uses Chilean pisco and Pica lime, and excludes the bitters and egg white. Other variants of the cocktail include those created with fruits like pineapple or plants such as coca leaves. Although the preparation of pisco-based mixed beverages possibly dates back to the 1700s, historians and drink experts agree that the cocktail as it is known today was invented in the early 1920s in Lima, the capital of Peru, by the American bartender Victor Vaughen Morris. Morris left the United States in 1903 to work in Cerro de Pasco, a city in central Peru. In 1916, he opened Morris' Bar in Lima, and his saloon quickly became a popular spot for the Peruvian upper class and English-speaking foreigners. The oldest known mentions of the pisco sour are found in newspaper and magazine advertisements, dating to the early 1920s, for Morris and his bar published in Peru and Chile. The pisco sour underwent several changes until Mario Bruiget, a Peruvian bartender working at Morris' Bar, created the modern Peruvian recipe for the cocktail in the latter part of the 1920s by adding Angostura bitters and egg whites to the mix.
