Even tastier than all of the baked goods prepared during the holidays are the delicious Christmas side dishes. My mom would exchange recipes with her sisters in Mexico every year. I believe that my siblings and I would agree that papas gratinadas was our absolute favorite out of all of the Christmas side dishes.
