God Father is a simple after-dinner cocktail made with a combination of equal parts scotch and amaretto. In order to prepare it, both ingredients should be poured into an ice-filled old-fashioned glass, then stirred. The cocktail became popular in the 1970s, and some say that it was inspired by the movie, while others say it was the favorite drink of Marlon Brando, who played the role of Godfather in the movie.
