Use thumbtacks, etc. to open a small hole in the side of the raw egg that is not too sharp, and then cook the egg in a conventional way, so that when cooking the egg, hot water will enter the eggshell, and the eggshell and egg white will naturally separate.
2. Use frozen eggs
Put the cold raw eggs taken out of the refrigerator into boiling water. Because there is a big temperature difference between boiling water and cold eggs, the eggs themselves will shrink, which makes it easy to shell.
3. Put it in cold water
Boil eggs in a conventional way, and then quickly put them in ice water for cooling, which is the same as the principle of "using frozen eggs". Because of the temperature difference, eggs will shrink.
Extended data:
Boil eggs that are not fresh for nearly 2 weeks. In this way, the eggshell can be peeled well without any effort. Because the egg white of fresh eggs contains a lot of carbon dioxide, carbon dioxide vaporizes when cooking eggs, so it becomes very difficult to peel eggs. As time goes by, carbon dioxide gradually diverges and becomes less, so stale eggs become easy to peel. The shelf life of eggs refers to the shelf life of raw eggs, so even if the eggs slightly exceed the shelf life, there is no problem if they are used by heating. However, please don't use eggs that are too old.
