Although originally from Peru, the Pisco Sour has gained popularity in Rio de Janeiro. This tangy and frothy cocktail is made with pisco (a grape brandy), lime juice, simple syrup, egg white, and Angostura bitters. The combination of the citrusy lime, the sweetness of the syrup, and the frothy texture from the egg white creates a unique and delightful drink. Sip on a Pisco Sour at a trendy bar in Rio and experience the fusion of Peruvian and Brazilian flavors.
