Combine the gin, freshly squeezed lemon juice, lemon syrup, vanilla extract, and egg white (or aquafaba) in a shaker with ice. Shake vigorously to chill and blend the ingredients.

Strain the mixture back into the shaker, discarding the ice, and perform a dry shake for added froth and texture.

Double strain the cocktail into a chilled cocktail coupe to ensure a smooth finish.

Garnish with several drops of lavender bitters to enhance the aroma and flavor.
