Instructions

1. Preheat your oven to 170 degrees
2. Slice the oranges into 1/4 inch slices.
3. Lay the slices on an oven safe rack, then place that rack on to a cooking sheet.  This will allow air to flow around the oranges as they bake.
4. Bake for 6 hours.  Turn the slices over every hour or so.  The oranges slices should be somewhat pliable when they’re done.  Start checking them diligently around the 5 hour mark.
