For one cocktail, you'll need:
- 2 oz gin
- 1 oz elderflower liqueur
- 1 oz fresh lemon juice
- 1/2 oz simple syrup
- Club soda
- Ice
- Lemon wheel and mint sprig for garnish
Use a London Dry gin for a classic taste. St-Germain is a popular elderflower liqueur brand. Make simple syrup by mixing equal parts sugar and hot water until dissolved.
