Cut a lime into quarters, and squeeze one quarter of the lime into the glass.
Gently stir to combine, and garnish with a fresh wedge of lime.
Notes
If you don't have St-Germain Elderflower liqueur, you can simply leave it out. The measurements for the remaining ingredients still make a perfect gin and tonic.
Make sure to use high quality tonic water for this drink. It makes a huge difference in the taste! My favorite is Fever-Tree Elderflower Tonic Water.
