Add all of the ingredients to a medium saucepan and place over medium-low heat. Simmer the mixture for 15-20 minutes, until the cranberries have burst and the sauce has reduced slightly.

Give it a taste (be careful, itll be hot!) and adjust the seasonings. You may want it to be a bit sweeter. Remove the cinnamon stick and discard. Transfer to the refrigerator to chill.

The cranberry sauce will thicken as it cools.
