Combine sugar, orange juice, and water in a large saucepan over medium heat. Stir to combine.

Add cranberries, salt, cinnamon stick and orange peel.
Bring to a simmer over medium heat, stirring frequently.

Continue cooking, for about 10 minutes, or until all or most of the cranberries have popped. I like to leave a handful of berries whole.

Let cool for at least 30 minutes. Cover and refrigerate until ready to use.
Can be made up to 3 days in advance
