How to boil an egg skin and peel it well?

Clever boiled eggs are easy to shell.

Eggs have high nutritional value, but shelling is not so easy. Today, we invited four children to have an egg peeling test to see how to peel the eggs more thoroughly. Look, we usually make boiled eggs by heating eggs in cold water. protein can easily stick to the egg skin. In this test, all four children failed.

It provides a wonderful way to boil eggs, and delaying the time of putting eggs can make the eggshells peel off easily.

Come and try this method. This time, let's wait until the water boils before releasing the eggs. This time, all four children finished the task of peeling eggshells quickly and well. Why is this? As we all know, eggs are composed of eggshells, inner and outer shells, protein and yolk. There is no gap between the egg membrane and protein. When cold raw eggs are put into boiling water, the eggshell expands rapidly when heated, so that a vacuum gap is formed between the eggshell and the egg membrane, and the two are separated. In this way, it is much more convenient to peel the eggshell, and the cooking time of the egg in water is shortened, and more nutrients are retained. Anyway, this ingenious method of cooking eggs is really good.
