How can I effectively dry out papaya seeds?

To effectively dry out papaya seeds, first remove them from the fruit and rinse off any pulp. Then spread the seeds out in a single layer on a paper towel or a mesh screen. Place them in a warm, well-ventilated area out of direct sunlight for about 1-2 weeks, stirring or flipping them occasionally to ensure even drying. Once the seeds are completely dry and hard, store them in an airtight container in a cool, dark place for future use.
