Combine the water and sugar in a medium saucepan and bring to a boil.
Add the cranberries, cinnamon stick, and orange peel. Reduce the heat and simmer, stirring occasionally, for 10 minutes or until the cranberries have "popped" and the mixture has thickened.
Remove from the heat, cover, and allow to cool to room temperature.
Remove the cinnamon stick and orange peel. Refrigerate until ready to serve.
