Straight from South America : Pisco sour cocktail

Rien de tel qu'un bon, un vrai, pisco sour, à Copacabana, en Bolivie, avec quelques amis... notez le blanc d'oeuf battu sur le dessus (indispensable pour faire un "vrai" pisco sour)

Ingredients :

· 1/2 botle of pisco (one botle is 740 ml)

· 1/3 botle Garabe de goma (sugar liquid) or few tablespoons sugar

· 1 mug fresh lime juice

· 1 egg whites 

· Ice cubes

Preparation :

In a blender, 8 ice cubes, pisco, Garabe de goma or sugar, fresh lime juice, and egg whites. Whirl until smooth (you'll no longer hear the ice cracking against the side of the blender) and serve straight up in a martini glass for example with a dash of aromatic bitters or cinnamon on the top.
