The sours, a very old cocktail family, consist of a mix of Brandy, lemon juice, sugar (or syrup) and (originally) egg white. They offer infinite potential for variations.
Pour the egg white, the syrup, the lemon juice, the Vodka and the mint leaves in a shaker cup. Dry-shake to blend the egg white. Fill the shaker with ice and shake vigorously. Strain in a chilled Martini glass. Garnish with a mint sprig, a cucumber slice, and a brandied cherry.
