Hey guys, have you ever seen egg that’s just about to go stale or already spoilt?

The other day, I was trying to make an omelette and proceeded to start breaking my eggs into a bowl. I got to the fourth and it turned out it was rotten. Sadly, I was breaking them all into the same bowl and the bad egg ended up spoiling the ones I’d already broken.

I didn’t know if I should cry or give myself a good beating for that terrible mistake. However, I learnt from that experience and now, I break each egg separately before add all together when making my omelette.

Fresh Egg Test #1: The Water Method

  • Get a pitcher or medium-sized glass bowl and fill it up with fresh water.
  • Gently place the egg into this and watch the result. If the egg is fresh, it will sink to the bottom and remain there. A slightly fresh egg will stand up on one end, the larger part to the top, while an old egg will float towards the top of the pitcher or bowl. The older the egg, the higher up it floats in the bowl.
  • As eggs get older, the air cells in the larger part expands and this explains why it floats when placed in water.

Fresh Egg Test #2: The Shake Method
You can also tell a fresh egg from an old one by giving it a shake. Since old eggs have larger air pockets at the larger parts, there is more room in the egg and they produce a sloshing sound when shaken.
Take the egg close to your ear and listen as you shake; a fresh egg will make little or no sound while an old one will.

Fresh Egg Test #3: The Crack Method
Lastly, you could just go right ahead and crack your egg into a bowl. An old egg will have a cloudy white with a yolk that is flat.

There you have it guys, three different ways to tell your fresh eggs from the old. Now you can actually avoid buying a wrong set.
