What is that strange white spot you see on raw eggs?

Why is the chalaza a sign of freshness?
The more visible the chalaza, the fresher the egg. In fact, over time, this structure fades and becomes less noticeable. This means that if you see this small white spot, it is good news: you have a very fresh egg in your hands. On the contrary, the absence of chalaza can indicate that the egg is less fresh.

Chalaza and the preparation of certain dishes
Although chalaza is not harmful, it is recommended to remove it in certain specific preparations such as custard. Its stringy texture could affect the smooth and homogeneous consistency of this type of delicate dish. Simply remove it using a strainer or spoon if necessary.
