Set aside a ½ cup of the cranberries.
Add the remaining cranberries and the rest of the ingredients to a medium saucepan over medium heat.
Bring to a slow simmer and cook about 10 minutes, stirring often.
Taste and add more sugar if desired and the cranberries you set aside earlier.
Simmer another 10 minutes, stirring often.
Store in the refrigerator. It should last a few weeks - discard if it smells funny or you see mold.
