In a large saucepan set over medium heat, combine the sugar, orange juice, and water. Stir until the sugar is fully dissolved.
Add the cranberries, a pinch of salt, the cinnamon stick, and the orange peel to the pot.
Bring the mixture to a gentle simmer, stirring frequently to prevent sticking. Continue cooking for approximately 10 minutes, or until most of the cranberries burst. For added texture, leave a few berries whole if desired.
Allow the sauce to cool for at least 30 minutes. Once cooled, cover the saucepan and refrigerate until ready to serve.
This sauce can be prepared up to 3 days ahead for convenience. Enjoy!
