Rinse the cranberries and remove any damaged ones.
In a medium saucepan, combine cranberries, water, orange juice, sugar, cinnamon stick, orange zest, and a pinch of salt.
Bring to a boil over medium-high heat, then reduce to medium-low.
Simmer for 10-15 minutes, stirring occasionally, until the cranberries burst and the sauce thickens.
Remove from heat and let cool completely—it will continue to thicken as it cools.
Discard the cinnamon stick before serving.
