This refreshing drink is similar to a Mojito, except that it is made with Gin. I made a larger batch in a pitcher instead of individually, topping each drink with tonic water at the end.
Add mint, lime, gin and sugar to a shaker and muddle. Add cucumber slices to shaker and shake vigorously.
Pour mixture over glass filled with ice and top with tonic water. Stir, let set for a few minutes for the flavors to enhance and enjoy.
