Add cranberries, sugar, orange juice, water, zest, and salt to a medium saucepan. If you’re using a cinnamon stick or ginger, add it now.

Bring to a gentle simmer over medium heat. You’ll hear tiny pops as the berries burst. Stir occasionally so nothing scorches on the bottom.

After about 8 to 10 minutes, most berries will have popped and the liquid will start to thicken. Taste and add more sugar if desired.

Remove from heat when it looks syrupy but still a touch loose. It thickens more as it cools.

Let cool for 15 minutes, then pour into a serving bowl or glass jar. Chill for at least 2 hours for the best set.
