Method
1
Fill a tall glass with ice cubes to chill the drink.
2
Pull a double shot of espresso (approximately 30-36ml) using your espresso machine.
3
Pour the tonic water over the ice in the glass.
4
Slowly pour the hot espresso over the back of a spoon or directly onto the ice to create a layered effect.
5
Gently stir the mixture once or twice to combine the flavors without losing too much carbonation.
6
Garnish with a slice of citrus fruit and serve immediately.
Barista note: Taste before adjusting — a small change in grind, dose, ratio, or time usually makes the biggest difference.
