Cut the half lime twice more and mash it with the sugar in the glass. Pour ice into the glass and top up with ginger ale. Finally, add the Blue Curaçao (add Blue Curaçao syrup for the non-alcoholic version).
Tip: Those who like it stronger can add 2 - 6 cl Chachaça. The cocktail tastes delicious even with sparkling wine instead of ginger ale.
