Chill your coupe glass by filling it with ice and water, then set aside.

Cut the lime in half and juice both pieces through a fine strainer into your shaker.

Pick 8 to 10 fresh mint leaves and gently bruise them in the shaker with a muddler or back of a spoon.

Pour in 2 ounces gin and 0.75 ounces fresh lime juice into the shaker with the mint.

Add 0.5 ounces simple syrup and stir gently to combine.

Fill the shaker three-quarters full with approximately 1 cup of cubed ice.

Seal the shaker and shake vigorously for 10 seconds using an up-and-down motion.

Discard the ice and water from your chilled glass and strain the cocktail into the glass using a Hawthorne strainer.

Garnish with a fresh mint sprig on top or across the rim before serving.
