Scottish bartender, Mal Spence of the Kelvingrove Café, created this play on the White Lady, a smoothed out Gin Sour made famous by Harry Craddock at the Savoy in London. Its creator, Harry MacElhone of Harry’s New York Bar in Paris, noted several different versions throughout the 1920s (including one with unsavory proportions of crème de menthe), but settled on a pared-down mix of gin, Cointreau and lemon juice with an optional egg white. Spence’s variation does away with Cointreau in favor of equal parts Cocchi Americano and yellow Chartreuse.
