Pour the apple cider into a medium-sized saucepan, filling it about three-quarters full.
Add the cinnamon sticks and whole cloves directly into the cider, arranging them so they are submerged and can release their warm, spicy aroma as it simmers.
If desired, add thinly sliced apple pieces to the cider for an extra layer of fragrance and visual appeal.
Place the saucepan over medium heat and slowly bring the mixture to a gentle simmer—this will produce soft bubbling and a lovely spicy aroma, indicating the flavors are infusing.
Once bubbling gently, reduce the heat to low to keep it simmering without boiling away too quickly. Continue to simmer for 30-60 minutes, stirring occasionally if desired, to allow the flavors to deepen and fill your space with warmth.
As the scent becomes rich and fragrant, remove the cinnamon sticks and cloves for a clearer, more balanced aroma, or enjoy the full spice infusion if preferred.
This simmering mixture is now ready to fill your home with cozy, spicy aromas—turn it off and let the fragrance linger to create a warm, festive atmosphere.
