A Brass Monkey is a type of cocktail made with rum, orange juice, and either dark or light creme de cacao. Making a Brass Monkey is quite simple; just add one part Captain Morgan Original Spiced Rum, one part orange juice, and one part dark or light creme de cacao to a cocktail shaker filled with ice.
Shake the mixture vigorously until it is well blended, then strain it into a chilled martini glass. Garnish with an orange slice and serve.
