As the saying goes: stick to eating one egg a day, and your body is healthier! Eggs are not only nutritious, but also one of the foods with the highest nutrient absorption rate of all foods! Boiled eggs are one of the most common ways to eat in daily life, which can taste the original fresh flavor of eggs, and it is not as troublesome as poached eggs, and it is not as greasy as omelette.
However, some friends said: Why when I boiled eggs, the eggs cracked before they were cooked, and the egg whites and yolks were boiled into the pot! Some friends said: Why boiled eggs, egg shells are particularly difficult to peel, sometimes buckle an eggshell, you can also bring a large piece of egg white, peeling up too much trouble!
In fact, boiling eggs seems simple, but there are also tricks. In daily life, some friends are accustomed to using cold water when boiling eggs, and some friends are used to boiling with hot water, in fact, whether it is with cold water or boiling eggs with hot water, it is not right! The following is to talk about the 3 tips of boiling eggs in detail, learn to ensure that your hard-boiled eggs, the eggshell is complete and not cracked, and the key egg is dehulled with a light touch!

Why is it wrong to say that boiled eggs in cold water and hot water are not correct? First of all, cold water boiled eggs, egg whites are easy to stick to the shell, especially the fresher the eggs, the more powerful the sticky shell, often when peeling eggs, not only will a large area of egg whites, resulting in waste, peeling up is also quite troublesome.
Secondly, boiled eggs in hot water, although it is conducive to the shedding of eggshells, the thickness of each eggshell is different, and the ability to withstand thermal expansion and contraction is different. Therefore, boiled eggs in hot water often cause the egg shell to crack when it is boiled to half-cooked, so that the egg white yolk in the semi-solidified state is directly cooked all over the pot!
In fact, boiling eggs is a chemical change in eggs! It is well known that raw eggs are colloidal inside and hard-boiled eggs are solid inside. Boiling eggs is the use of energy when heated, changing the molecular structure inside the egg, thereby changing, and producing new substances, and eventually forming an insoluble solid form.
To put it bluntly, what we think of as eggs boiled every day is the result of the internal curing of eggs! Therefore, boiling eggs with warm water is the most suitable! One is that warm boiled eggs are not easy to make egg whites stick to the shell; the other is that warm boiled eggs are not like hot water, making the eggshell crack!
Tips: Boil eggs in a pot of warm water, the water temperature can reach about 40 degrees, after the eggs are cooked, cook for 8 minutes on low heat, turn off the heat and simmer for about 3 minutes.
To be precise, when the water temperature reaches 58 degrees, the eggs will solidify and degenerate, and when the temperature of the yolk reaches 68 degrees, it will mature, but to achieve sterility, the temperature must reach at least 72 degrees. Therefore, if you cook in a pot under warm water for about 8 minutes, you can reach a sterile state. If you want to boil the eggs, cook for a little shorter time.

When boiling eggs, add a little white vinegar to the water to make the egg shell fall off better! Because the composition of the eggshell is calcium carbonate, when reacting with acetic acid, the eggshell will be softened, so that not only is the eggshell not easy to crack during the boiling process, but the softened eggshell only needs to be gently touched, and it is peeled off the shell gently!
Tips: Vinegar with the general family to eat and drink soup small spoon 2 spoons can be, this method is also suitable for making water wave eggs! With the same amount, the boiled water wave eggs are not only beautiful, the taste is tender, and the soup in the pot will not be turbid!

The final step in boiling eggs is to pass the cold water! Hard-boiled eggs, remember not to peel them directly! Although there is the assistance of boiled eggs in warm water and boiled eggs with vinegar, in order to make the eggs achieve the effect of gently touching and gently peeling off the shell, the boiled eggs must pass through the cold water! Again, the principle of thermal expansion and contraction is used to create a gap between the eggshell and the egg white, so that it is much easier to peel the shell again!
<h1 class="pgc-h-arrow-right" data-track="33" > chicken or egg first? </h1>
Chickens or eggs first, many friends have thought about this brain-burning problem! Now finally there's an answer! The answer is: eggs first, chickens later! Because, the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences, found a 610 million-year-old embryo fossil in the Guizhou Wong'an biota: the cage ridge ball! This embryo fossil, perfectly told scientists, is the first egg, then there is a chicken! Therefore, if there are "bear children" in the family who ask this question again, they can show it!
