Pisco Sour Date: 2008-07-25 From: Irene Gray Serves: 4 The egg white from a whole hen egg is too much for two drinks, but just right for four; a quail egg white is OK for two. Peruvian limes are traditional but US-standard Persian limes are too sharp (more appropriate for Caipirinhas; key limes work). Using raw sugar instead of syrup doesn't work: the sugar sinks to the bottom and doesn't balance the lemon, the drink will seem thin. 6 ounce Pisco (Machu Pisco brad) 2 ounce Simple Sugar Syrup (equal parts sugar and water dissolved) 3 ounce Lemon juice (about 2 lemons, freshly squeezed) 1 Eggwhite from Hen Egg 10 cubes Ice 4 dash Angostura Bitters Vigorously shake Pisco, Sugar Syrup, Lime Juice, Egg White and Ice in cocktail shaker for one minute -- froth the egg and chill down the drink. Pour into martini glasses. Garnish by floating drops of Bitters on the egg froth; draw a knife edge through the drops to create a pattern.
