Introduction: Egg Freshness Test 101

Picture of Egg Freshness Test 101

When baking, you not want only the finest ingredients for the optimum baking results, but you want fresh products.With summer events outside more or for those of us that save old egg cartons because we get our eggs from local farmers, I thought this egg test will help. So here is an easy and precise way to test the FRESHNESS of your eggs. Simply fill a large deep bowl with cold tap water and gently place your eggs, one at a time in the bowl. I hope this will save you both time and $$$$, as well as piece of mind, which is priceless!! Please feel free to share your thoughts and feedbacks in the comments below.

Step 1:

* If the egg sinks to the bottom of the bowl, then lays flat on it’s side, this means the egg very fresh and SAFE to use.

Step 2:

* If the egg goes to the bottom and stands, the egg is a few weeks old but still good to eat, but don’t postpone too long as it will go bad within 3-4 days.The further vertical the egg stands, the less fresh the egg is…. However, when in doubt, throw the egg out!!

Step 3:

* If the egg goes to the bottom then float to the surface, this means the egg is no longer fresh or safe to consume, so PLEASE DISCARD.

INTERESTING FACT: To tell if an egg is "raw" or "hard-cooked", spin it! If the egg spins easily, it is hard-cooked and when you stop a hard-boiled egg it just stops. But if the egg wobbles, it is raw. Also, when you touch the raw egg it stops, but if you let go again quickly it will start moving again.

Why step 101 ? You know more than one hundred ways to check egg's freshness !

Once the egg has been sunk, can we keep it for a later use or shall we eat it asap ? I mean eggs are porous, aren't they ?

I was taught this info by my grandmother when I was very young. Now that I raise chickens for their eggs, the knowledge is indispensable. Thanks for putting the info out there for everyone! Very cute and well done. The only thing I might add is, "How upright the egg stands tells you more exactly how fresh it is. The more upright it stands, the less fresh it is. Also, this is not necessarily an indicator of how old, but also how hot the egg has gotten before you get it."

No it's true, I remember doing that at school. Old eggs get air in them.

I am genuinely thank you for sharing your thoughts
about my egg freshness test.

Hmm someone should report that malitam for bad language, is no one moderating these comments?

The science behind this is that an egge is porous, so it basicalu breaths, the less fresh it is, the more the air has entered it, and thus it starts to give it buoyancy.

Great instructable!! I only learned of this a few months ago, I can imagine it being very useful to others as it doesn't seem to be common knowledge.

:) :-) :D
