This aquafaba-based fizz-style cocktail was created by mixologist James Grant at Black Lodge.

• 1.5 oz gin
• 0.75 oz Bols Blue liqueur
• 1 oz lemon juice concentrate
• 0.5 oz simple syrup
• 1.5 oz aquafaba (chickpea water)
• 1 to 2 oz soda water

Place all the ingredients except the soda water in a cocktail shaker with ice. Shake well, strain into a Collins glass, and top with soda water until the foam reaches the top of the glass. Garnish with a lemon twist. Serves 1.
