Heat a medium saucepan on medium-high heat. Add water, orange juice, granulated sugar, brown sugar, orange zest. Whisk until dissolved about 1-2 minutes.

Add in the cranberries and cinnamon stick and stir, cook until cranberries start to pop about 10 minutes.

Reduce heat and stir in Grand Marnier, Simmer another 3-4 minutes.

Remove cinnamon sticks and use an immersion blender (if you want it smooth) to blend the chunks out if desired.

Remove from heat and place in a serving bowl. Cranberry sauce will thicken as it cools.
