Before cooking eggs, it is very important to check their freshness by immersing them in a glass full of water.
Eggs, one of the most consumed foods in the world, should only be cooked if they are good and fresh. In general, it is always recommended to pay attention to the expiration date and preserve them as best as possible. Eggs are foods rich in protein and minerals, but they must be stored in the right way, so as not to have food poisoning.
To know why you should immerse eggs in glasses full of water before cooking them, I suggest you read carefully below.
Shelf life and storage of eggs
Fresh eggs can last up to 28 days, but it is best to consume them within twenty days of their laying to take advantage of their properties. As for supermarket eggs, you need to pay attention to the expiration date on the box.
When buying eggs, it is very important to check that they are intact, and that there are no bad smells. All fresh and edible eggs, once broken, have no smells, but if you smell a strange smell then it is better not to consume them. To avoid health problems due to the proliferation of bacteria, eggs should always be stored in the right way, avoiding temperature changes.
In general, eggs should be stored in the fridge, but if you want to keep them at room temperature, things change. It must be said that in the summer months they can last a maximum of five days, while in winter they can last up to two weeks.
If there is no indication of the expiration date, due to the faded date or if you do not remember how long you have had fresh eggs in the fridge, you can implement some simple verification methods. In addition, eggs in the fridge should be placed on the central shelves, so as not to contaminate the fridge with the microorganisms that are on the shell.
Soak the eggs in glasses of water
Fresh eggs can also be eaten raw or with quick cooking, the less fresh ones are better cooked in the oven. Understanding the freshness of an egg is not easy, however there is a very reliable home method. A good way to check if the eggs are fresh is to immerse them in glasses full of water.
This is a very reliable and simple method. Just take the eggs and immerse them in glasses or containers full of cold water, if the egg goes to the bottom it is fresh on the contrary it should be thrown away. Only the eggs settle on the bottom, instead of floating, then they are very fresh. In case the egg remains tilted inside the glass, then it is still edible. If the egg remains in the middle of the container, then it means that it should be consumed after being cooked. Theshells of the eggs have a certain porosity, so the eggs that are fresh have little air and are deposited on the bottom.
Methods for checking the freshness of eggs
In order to know if the eggs you have at home are edible and fresh, you can use different methods. In addition to the water method, there is a method that is based on the well-known technique of candling or light testing.
According to this method, which is suitable for experts in the kitchen, it is necessary to carefully observe the egg against the light. The egg will be fresh if the air chamber inside the egg is small, if it appears very dilated then it means that it has expired.
A great way to tell if the eggs are fresh is to break the eggs and take a good look at the shape of the yolk. If the yolk has the shape of a dome then it is fresh, if it is flat then it is not very fresh.
The egg mobility technique is a method that consists of shaking the egg to be checked and if you do not feel any movement it means that it is fresh. The presence of noise during the shaking of the egg means that the yolk is no longer dense.
