Combine the rum, grilled lime juice and simple syrup in a Boston shaker.
Add ice and shake well.
Strain into a chilled coupe or cocktail glass.
To garnish, use a hand-held kitchen torch to brûlé one side of the lime wheel, if desired. Thread the lime wheel onto an oversized toothpick and position across the top of the glass.
*To make grilled lime juice: Cut the fresh lime in half and set aside. Brush the grill grates with a little vegetable oil to keep the fruit from sticking. Rub olive oil on the skin side of the fruit. Next, place the cut side on the grill and let it cook for about 3 minutes, being careful not to burn the fruit. Run the grilled fruit through a juicer or reamer. The juice will keep in the fridge for 2 days. One lime will yield approximately 2 tablespoons of juice.
¾ ounce of grilled lime juice*
