Coppola Family Recipe
Believe it or not, the actual recipe that Clemenza uses in The Godfather is actually the spaghetti sauce recipe that the Coppola family used. So, if you're looking for the true Godfather experience, look no further!
The Orange
Coppola used the color orange and the fruit orange as a means of symbolism. The color orange in the film represented death. Whenever the orange fruit was shown, it was foreshadowing a death of a character in the scene.
