Wash orange thoroughly, be sure to give a gentle scrub of the skin as you will be eating the whole thing.

Thinly slice orange, you can use a mandoline to get consistent slices. Put aside for after.

In a large pan (think a lot of surface area as you don't want the oranges touching) bring water and sugar to a boil.

Gently add in your orange slices and cook until they become translucent, approx. 20-30 minutes.

Using a slotted spoon remove the orange slices and transfer to a cooling rack with a baking sheet underneath to catch the drips.

Enjoy on your favorite cakes or on its own!
