Brass monkey is a wonderfully zesty cocktail made with orange juice, dark rum, and amaretto. To make a perfect brass monkey, start by combining 3 parts of orange juice, 1 part dark rum, and 1 part amaretto in a shaker with ice. Shake vigorously for 10 to 15 seconds, then strain into a Collins glass filled with ice.
Finally, garnish with an orange wedge and enjoy!
