The cider can also be served warm. To do this, after simmering for 10 minutes, reduce the heat to low then add the rum. Strain and ladle into heatproof mugs or cups to serve.
Dark or gold rum can be used in place of spiced rum.
For a nonalcoholic version, do not add the rum and serve over ice or warmed.
Spicy Spiked Cider can be made ahead of time and kept in the refrigerator, ready to serve when guests arrive.
