Step 1

In a medium saucepan, bring the water, orange juice, and sugar to a simmer.

Step 2

Stir in the cranberries, orange zest and cinnamon stick, if using, and salt. Bring the mixture back to a simmer. Cook, stirring and mashing the berries occasionally, until the sauce has thickened. Note that it will thicken more as it cools.

Step 3

Discard the cinnamon stick and orange zest strips. Transfer to a bowl, cover and chill until you are ready to serve.
