How to determine the freshness of eggs
There are several ways to know about the freshness of eggs. But knowing such a thing that the longer the egg is stored, the easier it becomes, we chose the simplest option – to lower the egg into a glass of water.
If the egg drowned, then it is the freshest, 1-3 days since the chicken laid it; if the egg floats, but does not rise high, then the chicken laid the egg about 7-10 days ago. And if the egg is left to float on the surface of the water, the chicken laid such an egg more than 20 days ago.
Each egg is covered with a film from nature, which allows the eggs to be stored for a long time. Therefore it is not the best idea to wash it off before storing the eggs. Before preparing the eggs, it is better to wash off the film with water.
