Add water, cinnamon, ginger, lemon, cloves and black peppercorns to a pot.
Bring to a boil, then reduce heat to simmer for 5-7 minutes, or until you can smell the cinnamon.
While the ingredients are simmering, rinse, peel and chop the apple into bite-sized pieces.
Add the apple and simmer for 2-3 minutes.
Cut the heat, cover the pot, and let sit for 5 minutes, undisturbed.
Strain the tea to remove the contents and stir in honey if desired.
