Eggs expiry date: How to test eggs in water if you think they’ve gone off
Eggs are a breakfast, brunch or lunch staple as well as playing a key role in baking. They are an essential food item for any kitchen, but no one like’s a rotten egg. so how do you tell if those eggs sitting in your fridge are off? Well, that;s actually a really neat trick to try.
How to test eggs in water if you think they’ve gone off
The water test is a great way to tell if your eggs have gone off.
Sometimes eggs can still be eaten if they’re passed the sell-by date written on their container.
Most store-bought eggs kept in the refrigerator remain fresh for weeks beyond the stamped date.
One trick is not to store your eggs inside the fridge door.
That’s because that part of the fridge is the warmest as it generates heat every time the door is opened, therefore, making them likely to rot quicker.
A bad egg can cause food poisoning.
Eggs, cracked into containers, can be stored in the fridge for two days and up to 12 months in the freezer.
To test the freshness of an egg using water you’ll need a bowl or a glass.
Fill it up with cold water and put your egg in there.
If the egg sinks to the bottom and lays flat on its side, it’s still fresh.
If it sinks and stands on one end at the bottom of the bowl or glass, it’s not fresh but it’s still edible.

If your egg floats to the top then it shouldn’t be eaten.
The science behind this egg test is based on the fact eggshells are very porous and semipermeable.
That means air can pass through the shell, which causes the egg to float.
Over time, air enters through the eggshell and as a result, its shelf life diminishes the more air enters the shell.
The more air that enters the shell, the more buoyant the egg becomes.
There are other fresh tests methods you can use, though none of them are as effective as the one outlined above.
You can hold an egg up to your ear and shake it.
If you hear liquid swishing around inside, it’s gone bad but if there’s no sound then it’s good to eat.
The sound you can hear usually points to an old egg yolk that has become watery.
Another method is the good old smell test. If it stinks then throw the egg away.
When cracked, eggs should have a neutral odour, not a strong smell such as sulphuric, gassy, or sour notes.
Cracking an egg on a flat surface is another way of determining its freshness.
Fresh eggs will have a bright yellow or orange yolk, where the egg white is slightly stiff and sits up around the yolk. The white of a not-so-fresh egg will be flatter and spread out.
