Ode to the Pisco Sour

OK, no ode really, I'm in no mood for poetry. I am in the mood for pisco sour however. My mother and Greg were here last week and we tried just about every kind of pisco sour imaginable; the ginger sour, the mango sour, the green chile sour, the Angostura bitters sour, the chirimoya sour. I'm going to miss these.
