The reason why the skin inside the chestnuts fried in the air fryer cannot be peeled off is mainly due to poor pre-processing or poor selection of chestnut varieties.

The most perfect way is to cut a larger opening, preferably starting close to the bottom of the chestnut, just one side. This kind of chestnut can be easily torn apart with your hands in the opposite direction. The chestnuts peeled in this way are very complete, and the chestnuts can be peeled quickly. Wrong cuts are useless, and the key is to make the right words.

Notes:

Clean the chestnuts and make a small opening on the chestnuts with a kitchen knife. You can chop it horizontally or vertically. The opening should not be too big, just 1 cm. It should not be too deep, just cut open the hard shell.

The reason why the chestnuts need to be opened is because when the chestnuts enter the heated state, the inside will expand. In a closed air fryer, if the chestnuts are not opened, they will burst. Pre-opening can relieve pressure. Place the opened chestnuts into the roasting basket, use the nut button, and set the time for 15 minutes.
