Add the sugar, orange juice and zest to a medium saucepan over low heat.
Cook and stir the sugar until the sugar is completely dissolved.
Add the cranberries and ginger to the pan, continue to cook over low heat for 30 minutes until the mixture is at a low boil. (The mixture should be thickened a bit and almost the consistency of loose jam.)
Remove from the heat and allow to cool for 15 minutes.
