Thinly slice the oranges, you want around 15 to 18 slices. Set aside.
In a large skillet, that will fit all the slices in it, without much overlap, but deep enough to hold 3 cups of liquid, whisk together the cane sugar and water.
Heat on medium and bring to a simmer, and whisk until the sugar has completely dissolved.
Add all the orange slices in a single layer as much as possible to the skillet, and reduce the heat to medium-low so it is at a low simmer.
Let the orange slices simmer for about 60 minutes.
Using tongs, remove each slice and place them on a cooling rack. You can toss them in a little more sugar now if you want. Let them dry for 24-48 hours.
Use for cookies, cakes, breads, or dip in chocolate!
