I, similar to you, am barely frazzled once I crack an egg and see a spider-web-like string of white connected to the yolk. What’s it? And why did this occur to me? There are some foolish explanations and theories—perhaps it’s the egg’s umbilical wire, and even salmonella, the individuals say.
So in my grave private pursuit of discovering out what that white stuff is (an eggs-planation, if you’ll), I spoke to livestock and farm specialist Amy Barkely from Cornell’s Cooperative Extension. Learn on for solutions.
What’s that white stuff?
The white stringy little bit of an egg does certainly have a reputation—it’s known as the chalaza, (pronounced kuh-lay-zuh). “It’s basically egg white protein that has had the water wrung out of it. Because the egg clumps into its type, the protein across the yolk will type white strands that connect to each ends of the egg,” explains Barkely. The white strands are twisted in reverse instructions and anchor the yolk to verify it is centered within the shell. As an egg sloshes round—hey, carrying groceries on the subway isn’t simple—the chalaza will stability the yolk’s actions.
Why does it present up solely typically?
There are many elements that decide how simply you possibly can see the chalaza—the age of the hen being certainly one of them. “Youthful hens have a tendency to supply a extra bouncy, apparent chalaza,” Barkely says. “Older hens have weaker, waterier egg whites basically, which makes the chalaza much less distinguished.”
However the freshness of an egg additionally impacts the chalaza’s visibility. When an egg sits and matures in storage, the white will start to interrupt down or degrade. Due to that, the chalaza will disintegrate and develop into much less obvious over time, wanting extra translucent.

Can I eat it?
Undoubtedly. Though chances are you’ll be a bit postpone by the chalaza’s look, “it’s a 100% edible a part of the pure egg,” Barkely says.
After frying an egg, more often than not you gained’t be capable to discover the chalaza. It’s tough to search out it within the cooked egg white since they’re the identical creamy opaque shade. However you would possibly be capable to really feel the feel—Barkely describes it as “a bouncy ball feeling between your tooth.”
However what if I don’t need to eat it?
In case you’d relatively not eat the chalaza, merely take away it when the egg is uncooked.
There are a few methods to do that. Within the case of a fried egg, the place you’d wish to hold the egg intact, you possibly can take away the chalaza by pinching it out, utilizing kitchen instruments. Barkely shares, “I even have a pal who’s very, very against them. She has a devoted pair of tweezers that she makes use of to choose them off.”
While you need additional clean whisked eggs, like within the case of custard, a French-style omelet, or silky steamed eggs, you’ll desire a fine-mesh sieve (a hack we discovered from season two of FX’s The Bear). This method will catch all of the belongings you may not need—bubbles, eggshell, and the adamant chalaza.
