Sugar Syrup- Begin by adding the cups of sugar and cup of water to a pot. Bring the pot of sugar water to a boil, stirring occasionally until the has fully dissolved.
Orange Slice Simmer- Once the sugar has completely dissolved, add the orange slices to the pot of sugar syrup. Reduce the heat to a simmer and let the orange slices simmer for about an hour, or until they are translucent, stirring occasionally.
Air Dry the Orange Slices- Next, carefully remove the orange slices from the syrup. Transfer the oranges to a drying rack with a pan or parchment paper underneath to catch all of the drippings. Let the orange slices dry for at least a few hours or overnight until the oranges are a little tacky but not super sticky.
Dip Candied Orange Slices into Chocolate- Once the candied orange slices are dry enough to the point where they aren't too sticky but still a little tacky, heat up the chocolate, per the chocolate's instructions. Begin dipping the orange slices once the chocolate is melted. You can dip the orange slices by laying one side of the candied orange slice face down in the chocolate and using a rubber spatula to help evenly spread the chocolate on the orange slice. Or you can dip half of the orange slice into the chocolate. Completely your choice.
Add Toppings- Lay the chocolate covered orange slices to either a drying rack, parchment paper, or wax paper and add any toppings. Let chocolate dry completely before enjoying.
