8 large fresh mint leaves (plus 1 whole mint sprig for garnish)
1 lime, cut into ¼” thick rounds
1 tsp. sugar
¼ cup simple syrup (recipe below)
¼ cup Bacardi rum
Approx. ¼ cup soda water
Place the mint leaves, 2 lime rounds, and the sugar into a 10 ounce cocktail glass. Muddle everything together with a pestle or the end of a wooden spoon, working hard to crush the mint leaves and really smash the limes.
Fill the glass with ice and add the simple syrup and rum. Add another ring of the lime and pour the club soda to the top of the glass. Stir to combine so mint and lime are woven throughout the ice.
Garnish with a mint sprig and another lime round on the edge of the glass.
1 cup water
1 cup sugar
Combine water and sugar in a small sauce pan and bring to a boil, stirring frequently, until sugar is completely dissolved. Cool completely and then refrigerate in a jar or bottle for up to 1 month.
