You can try the following methods to cook eggs will not break:
1, soak in warm water
Eggs clean after not directly into the pot to cook, first soak in warm water for half an hour, especially from the refrigerator out of the eggs, direct cooking if the temperature difference is very large, the eggshell is easy to break. First soak in warm water to raise the temperature of the egg, and then boil the egg is better to cook, can prevent the egg shell rupture.
2, add salt or white vinegar
boiled eggs in the water with a little salt or white vinegar, you can soften the eggshell, so that the eggshell and egg white separate, so that the eggshell will not be easy to crack, and boiled is also easier to peel the shell. Especially with cracked eggs, as long as you add a little salt or white vinegar to the water, the egg white will solidify instead of flowing out, because salt has a coagulating effect on proteins.
3, cool water in the pot
Boiled eggs must be cool water in the pot, so that the temperature of the water and eggs together slowly rise, so that the egg shell is not easy to crack, the maturity of the egg, the taste will be better. On the contrary, if you boil water in the pot, the eggs are very easy to appear outside the cooked inside the raw situation, the eggshell is also very easy to cook broken.

Wash the eggs, with a sewing needle (ultra-fine kind) in the butt of the egg (fat end, not the tip of the end) to tie a small hole, do not tie too deep, not too hard, gently tie a small hole that can be. Because there is a gas chamber in the butt of the egg, so that when the egg is cooked, the gas inside the egg shell will slowly leak out through the small holes, and the egg shell will not rupture when cooked.
