1. Put the pork belly in a pot with cold water, you can boil the blood and remove the fishy smell (spices can help remove the fishy smell). The pork belly cooked in cold water will not have the smell of firewood.

2. Pork belly must be cooled before being cut into pieces, so that it is not easy to spill oil when frying sugar.

3. Use boiled water when the fried pork belly is boiled. At this time, the pork belly will not shrink when put into boiling water, and the pork belly cooked will not taste like firewood.

4. The cooking temperature must be controlled. After boiling, simmer for 1.5 minutes, and then simmer for about 45 minutes.
