Key Lime Pisco Sour

Contributed by Nick Fauchald

In the U.S., pisco sours are usually made with lemon juice, but fresh (not bottled) key lime juice tastes even better.

In a cocktail shaker, combine the egg white, pisco, key lime juice, simple syrup and 1 dash of Angostura bitters and shake vigorously for 10 seconds. Fill the cocktail shaker with ice and shake vigorously for 20 seconds. Strain into a chilled cocktail glass and top with 3 drops of Angostura.
