How to Make It
Bring cider, molasses, cinnamon, ginger, and orange quarters to a simmer in a medium saucepan over medium-high. Cover and reduce heat to low. (Do not allow liquid to boil.) Simmer until flavors are blended, 20 to 25 minutes. Remove from heat; pour through a fine wire-mesh strainer into a bowl or heatproof pitcher, and discard solids. Stir in rum, and serve warm.
