Zest the orange and set zest aside for garnish.
Juice the orange.
Add cranberries, sugar, orange juice (should be at least ½ cup) and ⅓ cup water to small pot. Stir, cover and bring to a low boil.
Uncover pot, reduce heat to simmer, and cook (stirring occasionally) ~12 minutes or until cranberries are audibly and visually 'popping' and cranberry sauce is thickened.
If sauce is too thick, add water 2 tablespoon at a time until desired thickness (note: sauce will continue to thicken as it cools).
Add salt to taste (careful it's hot!). Garnish with desired amount of fresh orange zest. Serve hot or cold.
