1 strip orange peel – about 1x3 inches, only the colored zest, optional
0.75 cups ground coffee – medium grind, for drip or filter
Instructions
Place the water in a medium nonreactive pot or, ideally, a clay olla and set it over medium heat.
Add the piloncillo, cinnamon sticks, and whole cloves to the pot.
If using orange peel, add the strip of peel to the pot, making sure to avoid any white pith.
Stir gently to help the piloncillo begin dissolving, then bring the mixture just up to a simmer over medium heat.
Once simmering, reduce the heat to low and cook at a gentle simmer for 10–12 minutes, stirring occasionally, until the piloncillo is fully dissolved and the liquid is fragrant with cinnamon.
Remove the pot from the heat and let the spiced syrup stand for 1–2 minutes so it is no longer boiling vigorously.
Add the ground coffee to the hot liquid and stir to fully moisten all the grounds.
Cover the pot and let the coffee steep off the heat for 5–7 minutes, until the grounds settle somewhat and the aroma is strong and well-rounded.
Line a fine-mesh strainer with a clean cotton cloth, coffee filter, or very fine sieve and place it over a heatproof pitcher or directly over individual mugs.
