The Porto-Vecchio Pisco Sour is a tangy and citrusy cocktail inspired by the beautiful town of Porto-Vecchio in Corsica. This cocktail is made with pisco, lime juice, simple syrup, and egg white. The pisco provides a smooth and flavorful base, while the lime juice adds a tart and zesty flavor. The egg white gives the cocktail a frothy texture and a silky mouthfeel. Shake all the ingredients vigorously with ice and strain into a chilled glass. Garnish with a lime wheel for an extra touch of citrus. Sip on this delightful cocktail and imagine yourself strolling through the charming streets of Porto-Vecchio.
