Rinse & Sort. Start by preparing the cranberries. Rinse the cranberries in a colander, discarding any visibly shriveled, bruised, or damaged cranberries. Drain any extra liquid.
Combine. Add cranberries to a medium or large saucepan. Add sugar, water, orange zest, orange juice, cinnamon, and salt.
Simmer. Bring the mixture to a simmer over medium heat, then when it starts to bubble, reduce heat to medium-low. The cranberries will start to swell and burst as they cook. Cook and stir regularly about 8-10 minutes, or until the sauce has thickened somewhat and most of the berries have burst. (The sauce will thicken even more as it cools). Taste and add more sugar, orange juice, or seasoning, as desired.
Serve and Store. Enjoy right away or chill for later. Store leftover cranberry sauce in an airtight container in the refrigerator up to 5 days.
