Ingredients:

16 cups (1 gallon) apple cider

1/4 cup light brown sugar

1 teaspoon allspice 

Pinch grated nutmeg 

2 teaspoons whole cloves 

1 orange 

Cinnamon sticks, for garnish 

Steps:

1. In a large pot over medium heat, add the apple cider. Stir in the brown sugar, allspice and nutmeg until the sugar is dissolved and bring to a low boil.
2. Stick the pointy ends of the cloves into the orange so that just the buds of the cloves are visible. The entire orange should be covered with the cloves.
3. Add the orange to the cider and reduce the heat to simmer. Cover and continue cooking for 20 minutes.
4. Serve in warm mugs with a cinnamon stick garnish.
