Caipirinha

1 lime (could alternatively use other citruses - ie: 1/2 tangerine)
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. (We have a long, wooden one from Brazil, made specifically for this purpose.) Just enough to release the juice, otherwise it'll get bitter. Add the cachaça and stir to mix. Add the ice and stir again. It is delicious and potent!

You can also make a pitcher of caipirinha. Figure out how many people and multiply amounts. If you can't find cachaça where you live, use a good vodka. The drink will then be called caipiroshka. No vodka? Use white rum and you will have a caipiríssima. Caipirinhas made with sake are all the rage in Rio now! Try one...We have a recipe for caipirinha made with tangerine, but you can also try the Brazilian fruit called lima, strawberries, kiwi, fresh passion fruit with mint, passion fruit with pitanga, watermelon, and so on.
