Cut half a lime in quarters and put them in a glass. Don't use just any glass. Presentation will never count as much as content, that's true, but make it the best you can.
Mash the lime. Punish it, have no mercy. Extract everything you can out of it. That's where you get Caipirão's somewhat sour and unparalleled taste.
Add the crushed ice. Have no fear. Add plenty of ice. This is the ingredient that makes everything even more intense and chilled.
Now to add the most important, the 6 tablespoons of Licor Beirão and stir.
And your Caipirão is done, just add two straws and enjoy.
