This refreshing cocktail combines crisp cucumber with the smoothness of sake, balanced by citrus notes and a touch of sweetness. The egg white creates a silky texture, making it a perfect choice for a sophisticated drink.
Muddle the cucumber slices at the base of a cocktail shaker to release their fresh flavor. Add the remaining ingredients and shake vigorously until the egg white becomes frothy and fully emulsified.
Drop in some ice cubes and shake again until the mixture is well-chilled.
Strain the cocktail into a pre-chilled glass filled with ice, then garnish with a cucumber ribbon before serving.
