Ingredients
Ice
45 ml gin
1 pasteurized egg white or 30 ml aquafaba (liquid from canned chickpeas)
22 ml lemon juice
22 ml simple syrup
15 ml crème de violette
2 dashes of lavender bitters (optional)
45 ml club soda, chilled
Lemon wheel, for garnish
Directions
Step 1
Fill a cocktail shaker halfway with ice. Add gin, egg white, lemon juice, simple syrup, crème de violette, and bitters. Cover and shake vigorously until the outside of the shaker is frosted, about 30 seconds.
Step 2
Strain the mixture into a measuring cup and discard the ice. Return the cocktail to the shaker, cover it, and shake until the pressure builds and the mixture starts to emulsify, about 45 seconds.
Step 3
Pour the chilled club soda into a glass. Slowly strain the cocktail into the glass, allowing the foam to rise. Garnish with a lemon wheel.
