Caipirinha
1 lime
2 tea-spoon of sugar
Crushed ice cubes
Cachaça (distilled from sugar cane)
Cut the lime in four and put in a cocktail glass, add the sugar, mash the lime quarters coarsely; Fill the glass with ice cubes, add the cachaça and stir well.
You can add vodka instead of cachaça - in this case, you get a caipiroshka.
