First of all, some suggestions about boiled eggs.
1. Under normal circumstances, after the eggs are cleaned again, they can be boiled in cold water with high fire for seven or eight minutes. Generally, it should not exceed 10 minute, because if the egg is boiled in boiling water for a long time, the protein structure of the egg will change and it will be difficult to digest.
It is recommended not to eat undercooked eggs. In addition to not being able to kill bacteria, it may also lead to lack of biological elements and unhealthy health.
Some people also like to put eggs after boiling water. Not bad, but not so delicious.
