Eggs have a huge advantage over most other foods. They can be stored in the refrigerator for a very long time. But not forever.
As a result, after breaking an egg, the kitchen is filled with an unpleasant smell.
Although the real problem is most often that spoiled food ends up in a bowl with normal food.
And then you have to throw everything away. Is it possible to determine the age of an egg before breaking it? Yes, it is possible.
The simplest method
If you have several suspicious eggs in your refrigerator whose age cannot be determined, you can use an express method to determine whether they are fit for food.
It's easy to do. Just place the egg in a tall container (glass, deep bowl) with water.
1. If the egg lies on the bottom, it is still quite fresh.
2. If it stands vertically on the bottom, it can be eaten, but you need to do it as soon as possible.
3. If it floats in water, it is better to throw it away.
There is no magic here. Eggshells are porous. Over time, moisture evaporates from the white, and air from the outside penetrates through the shell. The longer the egg has been lying, the more air there is inside.
That's why an old egg looks like a float that floats on the surface of the water.
