Spin the Egg Doneness Test

Place the egg on a flat or level surface. Give it a good spin. Hard boiled eggs will spin well. However, if there is a wobble noticed as the egg starts its spin this is caused by there still being some liquid inside which prevents a good spin.

Put the egg back and boil for another 1 minute and repeat.

This is the best and most simple test. I found it better than any of the other cooked egg testing methods below.

I would also not that a Raw Egg will not spin easily because of the inertia from the runny white and yolk that is not cooked inside the shell.

Shake the Egg Done Test

This is a good test to see if the boiled eggs are ready.

Start by doing a gentle shake of one of the to gently shake the eggs. Between your fingertips hold the egg, move it around in a circle – if the egg feels like it is solid it is ready. But if you feel a little liquidity – then put it back for another minute.

You can test or practice against an egg you know is raw to get the feel for it.

To be honest, this test does work but it requires more practice vs the egg spinning test above. By the time you do this, you could have finished the other test. Furthermore do not forget if you have just taken the egg out of the boiling water it will be hot and hard to hold for any length of time.

Egg To the Light Cooked Test

The thin shell of the egg should allow some light to pass through it. If it’s still uncooked, the yolk will be visible. When a boiled egg has solid white and center light will be unable to pass through and you can see the difference between a raw egg and a hardboiled egg.

IF you need more help try a flashlight and shine it from the opposite side of the egg. The egg is now between you and the light source. Now it will be a little easier to see if your egg is cooked. If you can see any yellow your egg is still not fully cooked. If you can not your hardboiled egg is ready.

I tried this test with a flashlight and was not able to get it to work on either a cooked or raw hardboiled egg.

Egg Doneness Test with a Thermometer

You can also use a quick read thermometer to test for doneness.

Carefully remove the egg in a spoon – discard the water – rest the egg on say a paper towel. Hold the infrared thermometer about 2-3 inches distance from the egg and if it reads above 160F the egg should be done. This is my least favorite method for testing is an egg hard boiled.

What I do not like about this method is that it requires the egg to be rest a little and this is a huge variable. Some people may rest it for 10 seconds others for 30 seconds and there is quite a difference in temperature result. This only worked when the egg was boiled for less than 2 minutes as some of the inside liquid has not yet been heated that much. The egg will be at a soft boil stage.

Egg Bubble Test Method

If the egg is uncooked it will release small bubbles when placed into warm water.  When the eggs go under the water tiny bubbles are released from the egg.

If the egg is completely cooked there will be no bubbles.

I tried this method and it does work, but the bubbles are very small and you must look really closely. So to be practical the egg bubble test vs the egg spin test – the egg spin test is better.


Crack the Shell To Test The Egg

This is kind of a final way – while you will know if the egg is hard boiled or not. But if the egg is not ready you have kind of wasted it.

Or. maybe you need to cook an extra egg if you are going to use this egg test.

Also, see in our video – where we cut an egg that has been boiled for 8 minutes – it has a tiny bit of liquid, but not the runny yellow yolk.

  • Take out one egg from the boiling pot.
  • Quickly run it under a cold water faucet.
  • Use a knife to crack the shell and cut the egg in half
  • Look at the yolk to see if it is how you like it.
  • If it is take out the rest of the eggs if you put them all in at a similar time
  • If it is nearly ready give them another 30-60 seconds

Do Hard Boiled Eggs Float when They Are Done

To begin with, don’t believe anyone who tells you that eggs floating in water are “bad.” This simply isn’t the case. When the egg is produced by the hen, an air sac is present at the pointy rounded end is tiny, but it develops in size as water is lost during storage. Therefore when   eggs age, they grow more bouyant and may “stand-up” or even float.

This does not indicate the egg is rotten; rather, it indicates that now the egg is old and has lost moisture. The great majority of them may still be utilised because they haven’t lost any nutrients or flavour. In the frying pan, the cracked egg’s form is more “flat.”

A hard boiled egg will have the same buoyancy as the egg before boiling as long as the shell has now cracked in the cooking process.

Boiling an egg for up to ten minutes causes it to become hard and cooked. If you cook it for 20 or 30 minutes or even hours, it will turn rubbery and overdone. When the proteins are heated, they uncoil and connect to form a solid interlinked set of molecules.  This changes a liquid raw egg into a solid, rubbery cooked egg.

Why Do Eggs Crack When Hard Boiled

The air within the egg air sac – expands as the egg warms up. As the heated air expands, it exerts pressure on the shell, causing it to split.

There are three ways you can stop the egg from cracking

  • You may avoid this by inserting a pin-pick into the round end (at the bottom) of the egg.
  • Another way is to Allow the eggs to reach room temperature before boiling them also helps to prevent breaking.
  • Or as we do in our video you can put them in the boiling water gently and slowly.
