The Carmen Puig papers document Carmen Puig's family ties to Jennings Cox, Puig's step-grandfather and the American credited with inventing the daiquiri cocktail. Cox was an engineer with Bethlehem Iron Works in charge of mines in Daiquirí, a town in Cuba's southeast region. Cox reportedly invented the famous daiquiri cocktail in 1898 by mixing together white Bacardi rum, mineral water, sugar, lemon juice, and crushed ice.

The Carmen Puig Papers include an original recipe for the daiquiri, while the bulk of the materials consist of family photographs. The papers also include some correspondence, clippings, and memorabilia; and materials related to Puig's career with the Bacardi company from 1965 to 1986.
