Toast the cinnamon sticks in a frying pan on a medium heat for 3 minutes.
Use a sharp knife to cut the top off the pumpkin to create a lid.
Next, prepare the pumpkin by using your hands to remove as many seeds as possible. Then use a spoon or an ice cream scoop to scrape down the sides to remove the loose flesh.
Add the pumpkin puree, spiced rum, orange juice, juice of 2 lemons, maple syrup, and cinnamon sticks into the pumpkin and stir to combine.
Add the orange and apple pieces, then finally add the ice.
Use a ladle to pour the punch into glasses and grate nutmeg on top to serve.
