I Want Fresh Eggs!

Ever wondered how you can identify a fresh egg from what is not? I have been reading about eggs and here are the things I have discovered on how to test if the eggs you are buying are fresh.

Generally, fresh eggs will lie on its side at the bottom of a bowl of water. Try this test: 

Carefully lower the egg into fresh cold water (do not use salt water)
     If the egg stay at the bottom - it is fresh.
     If the egg is at an angle on the bottom - it is still fresh and good to eat.
     If the egg stands on its pointed end at the bottom  - it is still safe to eat but best
     used for baking and making hard-cooked eggs.
     If the egg float - they're stale and best discarded. 


The yolk of a very fresh egg will have a round and compact appearance and it will sit positioned quite high up in the middle of the egg. The white that surrounds it will be thick and stays close to the yolk.  

A cloudy colouring to the egg white is a sign of extra freshness, as this "cloudiness" is in fact carbon dioxide, which is present when the egg is laid. Over time, the egg white will become more transparent, as the carbon dioxide dissipates.  
 

Question: But how can you do the above tests if you are in the supermarket buying your eggs? Here are some of the tests you can do.
  1. Observe how the egg sounds. Get the egg and proceed to gently shaking it while listening to how it sounds. An old egg will produce sounds of movement within it as you shake, whereas a fresh remains solid and does not produce any sound.
  2. Make use of a flashlight. Get a roll of toilet paper and proceed to affix it to you flashlight’s front area. Set it in such a way that no amount of light will be able to seep through around it. Now get your egg and place it front of the flashlight, the egg’s rounded area facing towards the light, before turning it on. If you notice bigger air spaces within the egg, you will know that it is no longer fresh.
  3. Sight and Touch - fresh eggs are rough and chalky, otherwise, it's soft and shiny
