In a shaker, add the cane sugar.
Squeeze juice from 3-4 of the lime wedges. Add all lime wedges to the shaker.
Using a muddler or the back end of a wooden spoon, crush the lime with the sugar, then give a quick stir.
Add ice to the shaker and pour the cachaça over it. Top the shaker with the lid and shake!
Pour the cocktail into a glass, garnish with the lime slice and enjoy!
