In a medium saucepan combine cranberries, pears, water, and honey. Bring the mixture to a boil over medium-high heat, then reduce heat to medium-low and cook, stirring occasionally, until cranberries burst and the mixture has thickened to your liking, about 5 to 10 minutes.
Remove the pot from heat and stir in orange juice, cinnamon, and orange zest.
The sauce will continue to thicken as it cools. Store in refrigerator.
