You crack an egg into a bowl and notice a thin white strand attached to the yolk. It may look strange, making you wonder if something is wrong or whether you should remove it. Surprisingly, that tiny strand is completely natural—and it can actually be a sign that your egg is fresh.
The strand is called the chalaza, a normal part of the egg’s structure. Its job is to keep the yolk centered inside the egg white, acting like a support that prevents the yolk from shifting too much. Most eggs have two chalazae, although only one is usually easy to see after cracking the shell.
The chalaza can also reveal how fresh an egg is. In fresh eggs, it appears thicker, firmer, and more visible. As the egg ages, it becomes thinner and less noticeable. So, spotting that white strand is often a reassuring sign rather than a cause for concern.
Because the chalaza is made of the same protein as the egg white, it is completely safe to eat. It blends into the egg during cooking and does not affect the flavor, texture, or quality of your meal. Most people never notice it once the egg is cooked.
There’s usually no reason to remove the chalaza unless you’re making recipes that require an exceptionally smooth texture, such as delicate sauces or desserts. For everyday cooking, it’s simply another natural part of the egg. Knowing what it is can replace uncertainty with confidence the next time you crack open a fresh egg.
