Looking for a cocktail for your next gathering that has an international flair? Look no further than this recipe for pisco sours, which 9-time traveler Eleanor N. from Annapolis, MD, enjoyed during her Discover South America: Chile & Argentina vacation. Her Program Director, Marta, was generous enough to divulge this supposedly “award winning” recipe, which she says will “impress your friends, your children, and certainly your teenage grandchildren!” Want to be the coolest? Whip up this batch, which will serve a crowd. (At least, with an entire bottle of pisco involved, we hope it will—but we’re not here to judge.) Do you have a recipe to share from your travels?

10 ice cubes
1 bottle pisco
10 Tbsp powdered sugar
1 egg white
5 oz. freshly squeezed lemon or lime juice*
A few dashes aromatic bitters (such as Angostura)
½ lemon or lime—with the rind!

*Ingredient note: Marta’s recipe called for lemon juice, but if you’re used to the Peruvian version of a pisco sour, lime juice may taste more authentic. Both are delicious, as is a combination of the two!

Combine all ingredients in a blender and blend until ice has melted. Strain into glasses, and enjoy!

Pisco sours are beloved all over South America—but you may be lucky enough to enjoy this version, as Eleanor did, with Grand Circle on Discover South America: Chile & Argentina.
