Wash the apples thoroughly under running water to remove any dirt or pesticides.

Core and quarter the apples. There's no need to peel them, as the skins will add flavor and nutrients to the cider.

In a large pot, combine the quartered apples, sliced orange, and water. The water helps to create steam and extract juice from the apples.

Add the cinnamon sticks, whole cloves, allspice berries, and brown sugar to the pot. Stir gently to mix the ingredients.

Cover the pot and bring the mixture to a boil over medium-high heat. Once boiling, reduce the heat to low and let it simmer for about 2 hours.

Stir occasionally to ensure that the apples are breaking down and releasing their juices. The mixture should become fragrant and the apples should soften.

After 2 hours, remove the pot from heat. Using a strainer or cheesecloth, strain the mixture into a large bowl or pitcher, pressing down on the solids to extract as much liquid as possible.

Discard the solids (or compost them) and return the liquid cider to the pot.

Taste the cider and adjust the sweetness by adding more brown sugar if desired. If you want a stronger spice flavor, you can simmer it for an additional 15-30 minutes with more spices.

Serve warm, garnished with a cinnamon stick or a slice of orange if desired.
