Many people are used to boiling eggs with shells and soaking them in cold water immediately, which can cool down and help peel them when peeling. As everyone knows, this practice is unscientific. It is best not to soak eggs in cold water after cooking. The correct way is to add a small amount of salt in the process of boiling eggs. Salt can not only sterilize and detoxify, but also form a certain gap between eggshell membrane and egg white membrane due to different shrinkage degrees, which makes eggshell peel off more easily.
