3 tablespoons gin (such as Hendrick’s) (1 1/2 ounces)
1 tablespoon fresh, strained lime juice (1/2 ounce)
1 ½ teaspoons simple syrup (1/4 ounce)
1 teaspoon Green Chartreuse (1/6 ounce)
4 large mint leaves, plus a sprig for garnish (optional)
In a cocktail shaker filled halfway with ice, combine the gin, lime juice, simple syrup, chartreuse, and mint leaves. Shake vigorously for 30 seconds, then strain into a coupe. Garnish with a mint sprig if you like, and serve.
Note: A teaspoon of Chartreuse may not seem like enough, but a little goes a long way and you can add more to taste if you like.
For a lighter cocktail, stir the drink with the ice, strain into an ice-filled tumbler, and top with fizzy water
