To make popcorn with a hot air fryer like the "Smart Air Fryer (EU Version)" from Xiaomi, you can try the following method:

1. Mix a few tablespoons of oil with the corn kernels.
2. Place the mixture in the fryer basket.
3. Cook at around 190°C for about 10 minutes.

However, it is important to note that results may vary, as hot air fryers are not designed specifically for making popcorn. Some people have reported that only half the kernels pop properly. Make sure you protect the resistance of the fryer to avoid any problems.
