How can I effectively dry orange peel?

To effectively dry orange peel, you can first wash and peel the Oranges, then spread the peels out in a single layer on a baking sheet. Place the baking sheet in an oven set to the lowest temperature and leave the peels to dry for several hours, checking on them periodically. Alternatively, you can air dry the peels by placing them in a well-ventilated area for a few days until they are completely dry.
