Caipirinha
1 lime
Half a lemon
2 ounces of cachaça
2 tablespoons of sugar
Ice cubes/crushed ice is better
Cut the lime and lemon into pieces and place them in a glass. Add 2 tablespoons of sugar and crush the pieces with a pestle. Add the cachaça and crushed ice. Stir it a little and vuala!
It's delicious and potent!

If you can't find
cachaça (made from sugarcane), use vodka or rum.
