Step 1: Dry Shake for the Perfect Foam
Start by adding gin, Green Chartreuse, fresh lime juice, simple syrup, and the egg white to a cocktail shaker. Do not add ice yet. Shake vigorously for about 15 seconds—this helps create a smooth, frothy texture that makes the cocktail extra luscious.
Step 2: Shake Again with Ice
Now, add a handful of ice cubes to the shaker and shake again for another 15-20 seconds. This chills the drink while further aerating the egg white, ensuring that signature foam.
Step 3: Strain and Serve
Using a fine-mesh strainer, pour the mixture into a chilled highball or coupe glass. This step removes any ice shards, leaving you with a silky-smooth cocktail.
Step 4: Add the Fizz
Slowly top the drink with club soda, pouring carefully to preserve the foamy layer.
Step 5: Garnish and Enjoy
Finish with a lime wheel and fresh mint leaves for an extra pop of color and aroma. If you're feeling fancy, sprinkle a touch of edible gold flakes on the foam for a luxurious finish.
