1. Wash the chestnuts
2. Cut the chestnuts into a mouth
3. Boil the chestnuts in cold water for 30 minutes. If you like, you can cook them longer to make them softer and more glutinous.
4. Chestnuts control dry moisture, prepare tin foil for air fryer
5. Mix honey and oil in a 1:1 amount (you can add sugar in a ratio of 1:1:1 if you like sweetness) and evenly spread it on the opening of the chestnuts6. Bake the air fryer at 300 degrees for 15 to 20 minutes. If you like a little burnt, you can adjust the temperature to 350 for about 10 to 15 minutes. Since the chestnuts are almost cooked, it just needs to be charred and dry, and that's it.
