My friends, this was my first time making the dried oranges and this is what I learned. Even if you are following a recipe it’s important to monitor how your oranges do in your oven.
I set my temperature to 250° and the cook time to 3 hours. By the second hour I started to smell burning and sure enough some of the oranges were getting a little toasty! I dropped the temperature to 170° and continued cooking for another hour. This was a better temperature for the oranges with my oven.
