In a cocktail shaker with ice, pour dark rum, orange juice, pineapple juice and cream of coconut.
Shake for 10-15 seconds until icy cold.
Using the cocktail shaker, strain into a glass filled with ice.
Grate fresh nutmeg over the top of the drink. Garnish with a pineapple wedge, a maraschino cherry and a paper umbrella if you wish.
Notes
Choose pulp-free orange juice for a smooth cocktail.
Serve with crushed ice if possible.
If cream of coconut is not available and you must use coconut cream, add a little sweetener (such as half an ounce simple syrup) to compensate for the difference.
