Pisco Sour

It's the national drink of Peru. It's bloody strong. And it's bloody nice. I already had plenty of it in Lima, in shot form; but tonight in Aguas Calientes, I had it as a cocktail. Vodka-like spirit, mixed with a kind of lemon juice concoction. Nice and tasty. And, of course, perfect preparation for tomorrow's dawn ascent to Machu Picchu.

Classy ol' Pisco.
