The Clover Club Cocktail is one of those classics that should live on in every mixologist's repertoire. According to The Old Waldorf-Astoria Bar Book the drink was first created at the bar of the Bellevue-Stratford in Philadelphia, a popular hang out for "literary, legal, financial, and business lights of the Quaker City" of the 1800's.
Today grenadine is often used in place of the raspberry syrup. However, I have to agree with Gary Regan in The Joy of Mixology when he advocates the use of raspberry syrup because "without it this drink isn't much to talk about."
The other essential ingredient in this drink is the egg white because it adds a great foam to the drink for a great finishing touch.
