This twist on a classic gin and tonic is the perfect summer cocktail. I assure you, it tastes as good as it looks.
Soak 4 slices of cucumber in tonic water for at least 8 hours, up to 24 hours.
In a cocktail glass, muddle the blueberries until nice and mushy. Place the ice cubes in the glass, and pour the gin over them. Pour in the tonic water, and stir until combined and blueberries have made the liquid a light pink color. Garnish with the remaining slice of cucumber. Then, get drunk!
