One of the most famous and popular products in the world are eggs. A versatile ingredient that can be prepared in a thousand different ways: soft-boiled, poached, fried or boiled. In some families, the egg is a staple food that cannot be missed at breakfast and is the center of breakfast.

However, in order to use it for a preparation, you have to open it. When you open an egg, you must first break the shell from which the yolk and the white come out. However, when these two elements fall onto the plate, you may notice a small white spot, usually near the yolk, which is much darker than the white. But what is it? Let’s find out.

When you open an egg, you may discover a small white spot near the yolk. Over the years, many have wondered what this is, but have not found an answer and have only made guesses. For a time, it was thought to be a vein or the umbilical cord of the chick. However, there is no doubt that these theories are wrong, but then what is it exactly?

The name of this place in raw eggs is calaza. Inside the shell there are two, one at the top and one at the bottom. These are twisted, thread-like strands of egg white that anchor the yolk to the top and bottom of the shell membrane, preventing the yolk from breaking even before the egg is opened. These strands are particularly visible in fresh eggs, but it is not necessary to remove them.

There is no need to worry about anything strange. On the contrary, as soon as the egg is cooked, the thread disappears and becomes a permanent part of the egg white. Its presence is also a sign of freshness, so it is good to notice it. However, if you want to cook something smooth and evenly colored, such as pudding, it is always better to remove this small stain.

Have you ever noticed those spots on the inside of an egg? Did you already know what they are?
