Notes
The quality of tonic water makes a big difference in this drink. Premium brands like Fever-Tree or Q Tonic work best.Store Lillet Blanc in the refrigerator after opening. It will stay fresh for about 3 months.For extra flavor, add a strawberry slice alongside the orange garnish.This drink works best with large ice cubes, which melt more slowly and keep the cocktail from getting watered down.Serve right away while the tonic water is still bubbly.
