Wash and quarter the apples (no need to peel or core). Place them in a large pot.

Add the orange slices, brown sugar, cinnamon sticks, cloves, allspice, and nutmeg to the pot.

Pour in the water, ensuring all ingredients are submerged. Bring to a boil over high heat.

Reduce heat to low, cover, and simmer for 1 hour, stirring occasionally.

After simmering, use a potato masher to gently crush the softened apples to release more flavor.

Strain the mixture through a fine-mesh sieve or cheesecloth into a clean pot or pitcher, pressing to extract all liquid.

Serve warm. Garnish with additional cinnamon sticks or orange slices if desired.
