Prince of Wales is a cocktail with several variations, but it is most often prepared with a combination of a liqueur such as Maraschino, champagne, Angostura bitters, sugar syrup, a pineapple cube, and either cognac or rye whiskey. In order to prepare it, all ingredients except champagne are shaken with crushed ice, then strained into a cocktail glass, and the cocktail is finished by the addition of champagne.
