5 to 6medium oranges - organic if you want to eat them and ideally seedlessYou can of course vary the citrus fruits and dry them at the same time as long as the thickness of the slices is the same.
Instructions
Wash the oranges and dry them well. With a sharp knife, cut them crosswise into thin slices (3 to 5 mm), trying to be as regular as possible.
Place the slices on the oven rack making sure that none of them can fall out. You can tighten them (they will retract as they dry) but be careful not to overlap so they can dry evenly.
Put them in the oven and dry them at 70 °C / 158 °F for 4 hours on rotating heat (if you have a dehydration mode, now is the time to use it!) Leaving the door slightly ajar to let the moisture escape . The kitchen will smell very good
After 2 hours, you can take a look to check that everything is going well and that no slice that has become smaller is found in perdition at the bottom of the oven. If your slices are a little thick, you can turn them over, if some are thinner than others and seem already dry, do not hesitate to remove them.
At the end of 4 hours, turn off the oven and let the oranges cool quietly. They will harden and take on their final appearance once they have cooled completely. You can now admire them and store them in an airtight tin box or glass jar where they can be stored for several months.
