Place the cinnamon sticks, cardamom, allspice, cloves, and star anise in a zipper-lock bag.
Crush the spices with a rolling pin. This will break them open and start to release the oils that help flavor the cider. You don't need to fully pulverize them, just break them apart.
Add the orange peel and peppercorns, and shake to combine.
To mull cider; add 4-5 tablespoons of the spice mixture to a tea sachet or bag and tie it off. Pour a gallon of cider into a large pot with the sachet, and heat until steaming, but not boiling. Turn off the heat and let steep for at least 15 minutes, or until the cider is as spiced as you like it. Then, allow the cider to cool before returning it to a jug for storage.
