1. Put the pine nuts in the pot and soak them in clear water for one hour. This will make the pine nut shell soft and easy to break.

2. Take out the pine nuts, put them in a steamer and steam them on low heat for 30 minutes.

3.30 minutes later, pour out the pine nuts, put them in a ventilated place to dry, and fry them with low fire after the shell of the pine nuts cracks.

4. Put the air-dried pine nuts into a wok and stir fry over low heat. During the period, the pine nuts in the wok were constantly stirred. After most of the pine nuts are opened, they can be eaten out of the pot.
