The method is as follows:

1. Use a paring knife to peel off the outer layer of the passion fruit peel, and then use a clean spoon to remove the inner part connected to the pulp. Dispose of cleanly.

2. The passion fruit peel can be placed directly in the sun to dry.

3. Cut the processed passion fruit peel into strips and spread it out directly in the sun to dry. After three or four days, the passion fruit peel will be dry.

4. In addition, the passion fruit peel cut into shreds can also be placed in a baking tray in the oven and dried directly in the oven. After drying, take it out to cool down and store it in a cool and ventilated place. That's it.
