Pisco Sour

Americans have a fear of egg whites in their cocktails. It's completely irrational, but we understand. The Pisco Sour is the perfect example of a cocktail that can be bolstered by the use of egg white. Without it, this cocktail is thin on the palate and almost astringent. With it, it's almost like key lime pie in drink form. Both Chile and Peru claim to have invented the Pisco Sour, though each has a slightly different variation. The Peruvian version is a bit more complex and has some added depth, so we'll stick with it. Many recipes actually call for Peruvian key lime juice, so if you're looking for a really authentic version, try to find some. Beware of recipes that call for lemon juice though, as this is likely a translation error from the Spanish word limón.
