Put everything in a cocktail mixer and shake vigorously. Strain into stemmed cocktail glasses.
Wash the lime and roll in on a board to loosen the juices. Cut the lime into about 8 pieces and place them in a double rocks glass. Sprinkle with the sugar and crush the limes with a pestle or large wooden spoon. Add the cachaca and stir to mix and dissolve the sugar. Add the ice and stir again. It's delicious and potent!
