If you're serving cake this holiday, and need to save time, do what I did here. Buy a white cake at the grocery store, and add some homemade touches like candied orange slices and I promise your guests will be impressed.
Making these candied orange slices was super easy. The only thing you need to be aware of is that your orange slices need time to dry, like two hours in a warm oven. Other than that, there's really nothing to it and the candied orange slices were delicious -- sweet, tangy, and chewy. They're definitely great for cake decorating, but you can serve them on their own as a candied treat, and your guests will eat them up!
