The Pisco Sour is a classic Peruvian cocktail that is perfect for enjoying in Chiclana de la Frontera. It is made with pisco, a grape brandy, lime juice, simple syrup, and egg white. The combination of the tangy lime and the frothy egg white creates a smooth and creamy drink. Served in a chilled glass, it is a popular choice for those looking for a unique and flavorful cocktail.
