Go get yourself a caipirinha.

1 lime

2 ounces of cachaça

Sugar to taste

Ice cubes

Wash the lime and roll it on the board to loosen the juices. Cut the lime into pieces and place them in a glass. Sprinkle with the sugar and crush the pieces (pulp side up) with a pestle. Just enough to release the juice, otherwise it'll get bitter. Add the cachaça and stir to mix. Add the ice and stir again.
