Because the eggs cooked in this way will be tender, and they should not be fragile when cooked, which will not affect the taste. Although under normal circumstances, when cooking eggs, you can cook them with cold water or hot water, but considering that the eggshell of an egg is fragile, if you cook it with hot water, the egg will be cooked with hot water at once, which will easily lead to the cracking of the eggshell, thus affecting the taste of the egg.
In our daily life, we boil eggs with cold water. Because the water temperature needs to rise slowly, it will take a long time to cook the eggs, and it usually takes about 15 minutes to cook the eggs completely. The main ingredient of eggs is protein, which is not very heat-resistant. If the heating time is too long, it will easily lead to protein solidification, making the boiled eggs dry and hard to eat. Therefore, the time for boiling eggs should not be too long.
How to boil an egg and peel it easily;
In order to adapt the eggs to the temperature, you can soak them in clear water for a few minutes before boiling them. At the same time, you can also clean the dirt on the eggshell surface by the way. Then you can add salt and vinegar to the pot, and then add the soaked eggs.
Add salt and vinegar to soften the eggshell. Vinegar is a weak acid, and eggshells are mainly calcium carbonate. There will be a weak chemical reaction between them. Remember to put the pot in cold water. If the water temperature comes up, add the eggs. Some people may think that it will be soon, but eggs with extremely low temperature will break easily because of the sudden increase in temperature.
Then turn on medium heat and slowly heat the water in the pot. Be careful not to open a big fire to make the water boil quickly, because the water will push the eggs to hit the inner wall of the pot, which will easily lead to the eggs being broken before they are mature. Generally, it takes about ten minutes to cook, and the boiled eggs should be put into cold water immediately. The effect of heat expansion and cold contraction will make eggs peel more.
