Combine cranberries, orange juice, and water In a large pot over medium heat. Bring to a boil, and then reduce the heat to simmer.
Let the berries simmer for around 20 minutes, stirring occasionally, until the berries have broken and the liquid is reduced to a jam-like consistency.
While stirring continuously to prevent burning, add in the cinnamon and nutmeg, and begin to add the honey or maple syrup gradually, around 60mL (¼ cup) at a time. Taste in between to get the sauce to your desired sweetness. I prefer it with around 180mL (¾ cup) of sweetener, but adjust it up or down to your liking!
Remove from heat and allow to cool to room temperature. Store in the fridge in an air-tight container for up to a week, or divide over smaller containers and freeze. This is also a perfect recipe to preserve through canning if you know how to do it!
