Squeeze 4 lime wedges into a Collins glass (or highball), then drop wedges into glass. Add 3 level bar spoons of raw sugar and 1 ounce club soda to glass.
Using a muddler, press and twist ingredients together a few times.
Stack mint leaves in your palm. Smack leaves with your other hand, 5 to 6 times, or until fragrant.
Rub leaves over the glass rim, then drop in.
Add rum to glass, then fill with ice. Top off with club soda.
Use a bar spoon to vigorously stir ingredients until drink is well mixed.
Serve drink immediately, garnished with a sprig of mint and a lime wedge, if desired. Enjoy!
Notes
Use your favorite dark or gold rum to make this drink. The recipe was not developed with spiced rum in mind, although you could try it. Just keep in mind that it's generally much sweeter, and of course, the spices will impact the flavor of the finished cocktail.Raw sugar has large crystals, some of which will remain after stirring. If you'd prefer no crystals, use a bar spoon to stir the the muddled limes, club soda, and sugar until better dissolved. Or you can make a simple syrup with equal parts raw sugar and water.See info before the recipe card for lots of tips and tricks for perfecting this cocktail!
