Pisco Sour

Lima, Peru — attributed to Victor Morris's bar, early 1920s, though Indigenous chicha traditions of pisco predate this

Peru's national cocktail is a precise emulsion of pisco (grape brandy), fresh lime juice, simple syrup, egg white, and Angostura bitters — shaken hard enough to generate a frothy white cap without diluting the spirit's aromatic complexity. The drink hinges on the quality of pisco: Quebranta or acholado for bold structure, Italia for floral notes. A dry shake first emulsifies the egg white, then a wet shake chills and integrates. Three drops of bitters on the foam are non-negotiable ceremony. The Peruvian version differs from Chilean in using lime not lemon, and in the mandatory egg white foam.

Served as aperitivo or between-course palate reset; bridges the gap between ceviche's acid and richer mains like aji de gallina; the foam tempers the sharpness for successive sips
