Steps
Mash the brown sugar, butter, cinnamon, cloves, and nutmeg with a fork into a smooth paste. Makes about 9 tablespoons of batter.
Into each of 6 mugs, add 1 1/2 tablespoons of batter and 2 to 4 tablespoons of rum. Pour in 3/4 cup boiling water per mug and stir until the sugar dissolves.
Garnish with cinnamon sticks or orange slices studded with cloves.
Tip: The batter keeps covered in the fridge for a week. Bring it to room temperature before using so it melts cleanly.
