Add the sugar and water to a medium saucepot. Stir to combine. Bring the water to a boil over medium heat, stirring to dissolve the sugar.
Rinse the cranberries, then add them to the boiling sugar water, and place a lid on top. Allow the water to come back up to a boil, at which point the cranberries will begin to pop.
Once all the cranberries have popped, remove the lid, give it a stir, and turn the heat down to medium-low. Let the pot continue to simmer over medium-low heat for 5-7 minutes, stirring occasionally, or until the cranberries have completely broken down and the mixture has thickened. You can simmer longer if you prefer an extra thick sauce.
While the cranberries simmer, zest and juice the orange
Once the sauce has thickened, remove it from the heat and stir in2 Tbsp orange juice and 1/4 tsp zest to the sauce. Allow the sauce to cool slightly, then serve.
