The Clover Club Cocktail is a cocktail consisting of gin, lemon juice, raspberry syrup, and an egg white. The egg white is not added for the purpose of giving the drink flavor, but rather acts as an emulsifier. The Clover Club Cocktail is a drink that pre-dates Prohibition in the United States, and is named for the Philadelphia men’s club of the same name, which met in the Bellevue-Stratford Hotel at South Broad and Walnut Streets in Center City. The Clover Club was chartered in 1882.
