In a medium saucepan, combine the fresh cranberries, granulated sugar, orange juice, orange zest, and water.
Place the saucepan over medium heat and bring the mixture to a simmer, stirring occasionally to dissolve the sugar.
Once the mixture comes to a simmer, reduce the heat to medium-low and let it continue to simmer for about 10-15 minutes, or until the cranberries burst and the sauce thickens to your desired consistency. Stir occasionally to prevent sticking.
Taste the sauce and adjust the sweetness if needed by adding more sugar, if desired.
Remove the saucepan from the heat and let the cranberry orange sauce cool slightly before serving.
Transfer the sauce to a serving bowl or jar, and refrigerate until ready to serve.
Serve the cranberry orange sauce alongside your favorite dishes, such as roasted turkey, chicken, or pork.
