1. Soak the eggs in water. Before boiling them, it is best to soak them in cold water, and then boil them in a cold water pot, so that the eggshells will not break easily when cooking. Of course, this is just one way to keep the egg shell intact.

2. Firepower. When boiling eggs, if there is a fire, it is easy to make the air in the eggshell expand rapidly and cause the eggshell to burst; If you use a small fire, it will not only prolong the time of boiling eggs, but also make it difficult to master the tenderness of eggs. Therefore, it is most suitable to boil eggs with medium heat.

3. Time determines the size of firepower. As long as the time of boiling eggs is accurately mastered, the degree of tenderness of eggs can be controlled at will. Boil soft eggs. Boil the water for 3 minutes. At this time, the egg white is solidified and the yolk is fluid; Boil boiled eggs for about 5 minutes after boiling. Boiled eggs, the egg white is solidified, while the yolk is in a thick liquid state, soft and smooth; Boil hard eggs, just boil for 7 minutes. At this time, the egg white is solidified and the yolk is dry.

4. Stirring: In order to make the egg yolk solidify in the middle of the egg white, after the egg is put into the pot, it should be stirred in one direction continuously with a spoon to make the water in the pot swirl until the egg is cooked.
