2-3 ounces tonic water, lime wedge
Best gin to use: A London dry gin makes the best gin and tonic. We nearly always use Tanqueray. Best elderflower liqueur: St. Germain is the most popular but we also love Drillaud. It's similar in flavor for a fraction of the price. Best tonic water: Skip the grocery store brands and go with Q Mixers or Fever Tree tonic waters. Their superior flavor makes a big difference.Squeeze that lime wedge! The lime wedge is not just for looks. Make sure you squeeze it into your drink to release its juice. Stir before serving. It's easy to overlook this step but if you do, you'll immediately notice how unbalanced your drink is. Non alcoholic option: Substitute a non alcoholic "gin-like" spirit for the gin and elderflower cordial for the elderflower liqueur to make an alcohol-free drink.
