Boiled eggs are not broken, and there are generally methods such as needle sticking and cold water soaking.

1. Acupuncture method: After the egg is washed, use a household sewing needle to puncture a small hole in the bottom of the egg (the fatter end, not the pointed end). Don't tie it too deep or too tight. Because there is an air chamber at the bottom of the egg, after the egg is cooked, the air in the eggshell will slowly leak out through the small holes, and the eggshell will not break.

2. Soak in cold water: After washing the eggs, soak them in a basin filled with cold water for half an hour to reduce the air pressure inside the eggs, then put them on the fire, boil the water for 5 minutes, and then soak them for 5 minutes after turning off the fire, so that the eggshells will not be broken.

Water must drown the eggs. Many people add a little boiled eggs to save natural gas. In fact, this can easily lead to uneven heating of eggs, leading to egg rupture. We must pay attention to this.

Controlling the temperature is also important. If the fire is too large, it will produce a certain air pressure on the egg liquid, which will make the egg liquid expand outward and lead to the rupture of the egg. If it is a small fire, although the egg will not be broken, the nutritional value of the egg will be lost because it is cooked for too long, which is not conducive to the human body to absorb the nutrients.

Boil eggs over medium heat, preferably for no more than ten minutes. If the time is too long and the eggs are overcooked, the nutrients will be reduced.

In addition, adding salt to boiled eggs is also one of the keys, because salt can not only prevent eggs from cracking, but also make them easier to peel. Generally, a family can cook 5 eggs with 1 g salt.

How to peel an egg quickly?

Boiled eggs are put into ice water, and then peeled, and the whole shell will fall off by itself.
