Add ice to your cocktail shaker along with the rest of the ingredients (lime juice, rum, syrup, fruit punch, pineapple juice, cinnamon and nutmeg).
Shake vigorously 10 times and pour over ice.
If you're using a rum punch bowl, pour all the ingredients into the bowl and give it a good mix. Leave to sit for a little while before serving over ice.
Notes
The cinnamon and nutmeg are optional, but once you try them, you won't make your rum punch without them.
Remember to leave the rum punch to sit for a little while before serving if you make it in a bowl. Don't add ice!
One serving in the hurricane glasses I used is 420ml or 14oz.
