A riff on the Ramos Gin Fizz →
Add all ingredients except the soda water to a cocktail shaker and vigorously dry-shake (without ice) for 15–20 seconds.
Add 1 square ice cube and 1/4 cup crushed or pebble ice. Shake until you can’t hear the ice.
Aerate the cocktail once by pouring it from one shaking tin into the other, drawing your hands apart as you do so to increase the distance of the pour.
Gently pour into a chilled Collins glass. Place in the freezer and keep undisturbed for 5 minutes.
Remove from the freezer and carefully separate the edge of the foam from the rim of the glass with a metal pick.
Slowly add soda water down the center of the drink, making sure the foam is nice and thick and rises above the rim of the glass.
Insert a metal straw directly in the middle of the foam and dust with matcha.
