Method
Cocktail Preparation
Mix the Base Ingredients
In a cocktail shaker, combine the Roku Gin, elderflower liqueur, fresh lemon juice, and egg white.
Dry Shake
Dry shake (without ice) the mixture for about 15 seconds to emulsify the egg white, creating a frothy texture.
Wet Shake
Add ice to the shaker and shake again vigorously for another 15-20 seconds until well chilled.
Strain into Glass
Strain the mixture into a chilled coupe or cocktail glass.
Prepare Vermouth-Lemon Foam
In a separate small bowl, mix the dry vermouth with a little bit of lemon juice and whip until foamy. Spoon this foam gently on top of the cocktail.
Garnishing
Prepare Lemon Zest
Use a vegetable peeler or knife to create a strip of lemon zest.
Garnish Cocktail
Garnish the cocktail with the lemon zest strip by placing it on the foam top.
