Pisco Sour is a cocktail that originated in Peru but has become popular in Barcelona as well. It is made with pisco, a grape brandy, lime juice, simple syrup, and egg white. The egg white gives the cocktail a frothy texture and adds a creamy element to the drink. Pisco Sour has a balanced combination of sweet, sour, and bitter flavors, making it a unique and enjoyable cocktail.
