Obviously, if all you have is gin and lemon and orange liqueur, a white lady is an excellent cocktail. The addition of Luxardo is meaningful, though. The above quantity is for one cocktail but I'm making them for four people tonight. I use a Pyrex measuring glass and pour in a cup of gin, then add 3 ounces each of the lemon and cointreau, bitters and two dashes simply syrup (because the Cointreau isn't quite sweet enough to balance the lemon). I then add the egg white and buzz with a hand blender. I fill it with ice to chill the cocktail and pour into four glasses over a big ice cube.
