White hard boiled eggs will crack and this has to do with the freshness of the egg itself and the cooking method. Many people on the internet say that if the egg is not fresh it will be broken or fresh. But I don't feel much about this because I don't know how fresh the egg is. But this cooking method is definitely relevant.
First of all, eggs should be cold eggs, not at room temperature or from the refrigerator. If you take an egg out of the fridge and put it in hot water, do you think it is fried? Splitting is already controlling your emotions. It's not good to categorize everything.
Secondly, you can't put eggs directly in boiling water. After washing the eggs at room temperature, the water in the pan should not become hot. It's best to place the eggs in a pot of cold water and heat them slowly. Wait for the water to turn on and cook for 5 to 6 minutes, then turn off the heat for a few moments. Of course, there are many so-called methods: boiling eggs with salt, boiling eggs with vinegar. But I think it's normal temperature and related to the cold water port, and these two ways are enough.
How to boil an egg has been simple, easy to use for more than 10 years and does not boil the protein. First of all, the egg has an air chamber in its large head and knowing that the principle of contraction of hot and cold water breaks the shell, you can understand why the egg boils. The exact task is to put:Boil water in a small pot of milk, and with the tip of a small knife gently boil the large head of the egg into a small hole, which plays an important role in the contraction. Usually, five and a half eggs may take five and a half minutes, and the yolks are served with a bowl of oatmeal porridge, which contains a small, rich, sweet and olive oil.
