Step 1

Fill a shaker three-fourths of the way with ice. Add the gin and lime juice. Add the simple syrup. Cover and shake for 10 to 15 seconds or until condensation forms on the outside of the shaker. Editor's Tip: Shaking until you see condensation on the outside of the shaker is just a marker. It means you're shaking long enough to chill and mix the ingredients properly. Too little shaking and the finished cocktail won't taste as balanced, nor will it be icy enough.

Step 2

Strain the drink into an ice-filled glass. Garnish with lime. Editor's Tip: Lime wedges, half moons and full wheels (or slices) all work here.
