One of the I.B.A. official cocktails, the Pisco Sour is a South American cocktail touted by both Chile and Peru as their national drink. Both countries also claim ownership of it's creation, however, most facts point to the cocktail being invented sometime between 1915 and 1924 by American bartender Victor Vaughn Morris at Morris' Bar in Lima, Peru.
Morris' original recipe has never been found but most likely it was akin to a basic sour that employed Pisco as the base. Later versions would refine this into something closer to the I.B.A. recipe for this cocktail:
1.5 Oz. Pisco
1 Oz. Lemon Juice
3/4 Oz. Simple Syrup
1 Egg White
Shaken with ice then strain into an Old Fashioned glass and garnish with a few drops of Angostura Bitters.
Peru's version uses Peruvian pisco Key lime juice, syrup, ice, egg white, and Angostura bitters. The Chilean version uses Chilean Pisco, Pica lime but excludes the bitters and the egg white.
My version heads a little towards Hawaii.
1.5 Oz. Pisco
2 Oz. Fresh Pineapple Juice
1 Oz. Fresh Lime Juice
1 Oz. Pasteurized Egg White
1/2 Oz. Agave Syrup
2 Drops Angostura Orange Bitters
Garnish: Pineapple Chunk and
Combine all the ingredients in a cocktail shaker WITHOUT ice and (dry) shake vigorously for 15 seconds to emulsify the egg white. Add a cup of ice then shake vigorously again for another 15 to 20 seconds. Strain into a chilled Old Fashioned glass, express the lime slice over the cocktail, drop in then tap an extra drop of bitters onto the foamy cap and slip the garnish in and enjoy.
The first Saturday of February is National Pisco Sour Day.
