"This New Orleans classic was coined in 1888 by the Ramos brothers, who owned and operated the Meyer’s Table d’Hotel Internationale bar. You should always “dry shake” any drink with egg white which means simply shaking first without ice. Then follow with another hard shake with ice. Dry shaking helps emulsify the egg white into the other ingredients and also creates the lovely foam on the top of the cocktail."
