1. Prepare materials.

2. Cut the beef into strips and slice the onions.

3. Mix all the ingredients together, stir with your hands, and marinate in the refrigerator for more than 2 days.

4. String with bamboo skewers.

5. Place it in a ventilated and cool place to air dry for about 2 days.

Looks like 6.2 days later, there is very little moisture left.

7. Take it out of the bamboo stick, put it in the oven, and bake it at low heat. Bake it several times for a short time to avoid the meat being too dry or burnt if the fire is too high or the time is too long. It depends on the power of your oven, the thickness of the meat, and the drying condition.
