Dulce de leche, made with copious amounts of Baccardi in milk, is the drink Sky Masterson uses to attempt the seduction of Sarah Brown in "Guys and Dolls." When Sarah balks at an alcoholic drink he assures her the alcohol is only to keep the milk from spoiling, and she says it would be a wonderful way to get children to drink milk. Next thing you know she's singing in a fountain.
A dangerous drink indeed.
