2 tablespoons orange liqueur - such as Triple sec or Grand Marnier (you can also use orange juice as a substitute)
Instructions
Place the water and sugar in a medium saucepan over medium-high heat, stirring occasionally to dissolve the sugar. Stir in the orange zest and cranberries and bring to a boil. Reduce to medium and simmer until slightly thickened, and about 1/2 of the cranberries have popped open, about 5 minutes. Take off the heat and add the orange liqueur. Transfer to a non-reactive bowl (glass or ceramic) and cool to room temperature. Serve at room temp.
The cranberry sauce can be refrigerated for up to 5 days. Let it stand at room temperature for at least 30 minutes before serving.
