Combine ¾ cups water, ½ cup sugar, and ¼ cup maple syrup in a medium sauce pot. Bring to a boil.
Once boiling, carefully stir in the cranberries. Reduce to a rapid simmer, simmering until the cranberries have all burst, about 10 minutes.
Zest one of the oranges. Juice both oranges. Stir¼ cup orange juice, ¼ teaspoon cinnamon, and ⅛ teaspoon nutmeg into the cranberry sauce. Taste for sweetness and orange flavor, adding the remaining ¼ cup of sugar if desired. Add the orange zest for a stronger orange flavor, if desired.
For a thicker sauce, simmer over medium-low to evaporate off some of the liquid. Let cool to room temperature before transferring to the fridge to cool completely. This will take about 2 hours.
Notes
This cranberry sauce freezes very well! In fact, I froze the cranberry sauce from these pictures and plan to thaw it for Thanksgiving day.
Let the sauce thaw overnight in the fridge, then reheat on the stove. If you forget to thaw it, no worries; just add it to a sauce pot with a splash of water and stir frequently over medium-low heat, until thawed.
