Wash oranges well. Cut the ends off the orange and discard. Slice remaining orange into ¼ inch thick slices.

In a large pot over medium high heat, stir the water and sugar until the sugar is dissolved. Bring to a gentle boil and add orange slices.

Reduce the heat to med low until it is just barely simmering. Cook oranges until they are translucent, turning over at least once. 40-60 minutes depending on the size of the orange slice.

Remove orange slices from the pot and place on a wire rack over a baking sheet covered in parchment paper to cool and harden at least 2 hours or overnight.

Melt chocolate in a double boiler, dip half the orange in and them place them on parchment paper or a silicon mat to harden at least an hour. Store them in an air tight container on the counter for 1 week or in the refrigerator for a month.
