1. Punching holes to prevent cracking is to prevent salted eggs from cracking. Before cooking, you can prick a small hole with a needle at the bigger end of the salted egg head, and then put it in water to cook. If the salted egg is cracked, just add some vinegar and salt to the water and the protein will solidify.

2. Soak the salted eggs in cold water. First, soak the salted eggs in cold water for a while, and then boil them in a cold water pot, so that the eggshells are not easy to break.

3, medium fire cooking is the most suitable. When cooking salted eggs, it is easy to cause the air in the eggshell to expand rapidly, which will lead to the eggshell bursting. If using small fire, it will prolong the cooking time of salted eggs and it is not easy to master the tenderness of eggs. The best way to boil salted eggs is medium heat.
