This cold lemonade Caipirinha is asweet blend of citrus juice and cachaca, Brazil's infamously potent sugarcane spirit.
With a wooden pestle or spoon, crush lime wedges and sugar in a large glass until juices are released. Stir in cachaca. Fill a pitcher with ice; add cachaca mixture, and stir. Stir in lemonade; divide among serving glasses. Garnish with lime-peel twists and lemon slices, if desired.
