Crack the shell to make it easier to peel

Q: How To Easily Peel A Hard-Boiled Egg?

A: Hard-boiled eggs peel easily when you peel them in water. Peel in an ice bath or under running water. Start with the larger end of the egg, as this is where the air pocket is. Crack the top of the egg and start peeling the shell off and then work around the egg in water to help the yolk slide off the shell. Eggs also peel easier when you place them in an ice bath for a few minutes to cool after cooking.

Eggs in ice bath

Q: What is an ice bath?

A: An ice bath is a bowl of cold water with ice cubes. An ice bath helps a hot boiled egg cool quickly and the egg white will shrink from the shell, making it easier to peel.

Q: Does the color of the egg shell matter?

A: There is no difference between white or brown egg shells. The quality of the egg is the same. Different hens lay different color egg shells. Boiled eggs do not change color when they are boiled.

Q: How long do eggs last?

A: For uncooked fresh eggs. Check the date on the carton when you buy them. You want the date to be use by date to be the furthest from the current date and the packed date to be as close to the current date. Eggs will last the longest if kept in the refrigerator. Eggs will last on average for 3 to 5 weeks. For boiled eggs, they will last for up to 5 days in the refrigerator.

eggs in the refrigerator door

Q: Should I keep fresh eggs in the egg holder on the refrigerator door

A: Fresh eggs keep best located further in the refrigerator and in their own carton. Eggs kept in the egg containers in the refrigerator door are exposed to temperature fluctuations every time the door is opened. The heat will deteriorate eggs quicker. Stable cool temperature with eggs kept in their protective carton towards the back of the refrigerator keeps them fresher longer.

Fresh egg

Q: How to know if an uncooked egg is fresh

A: When you crack an egg the white will look like one of three ways

  1. If the egg white is a little cloudy – the egg is fresh
  2. If the egg white is clear – the egg is a little older but still edible
  3. If the egg white is iridescent – the egg has more than likely gone off and should be thrown away

Q: Does it matter how many eggs I cook at the same time?

A: As long as the eggs are in the pot in a single layer, you can boil eggs one or 10 at the same time and they will all cook the same, for the same time.

egg carton

Q: Which way should an egg be stored – large end up or down?

A: If you notice when you buy store bought fresh eggs, they will have the smaller point of the egg nestled into the egg carton and the larger top of the egg exposed. This is because the air pocket is located at the top of the egg. This is the ideal way to store eggs, especially if you get them farm fresh and they come packed both ways, you can re pack them with the smaller pointer ends down and will help them maintain their shape longer.

Q: Is it necessary to keep eggs in the refrigerator

A: In the USA, yes it is necessary to keep fresh eggs in the refrigerator. The reason is that eggs are washed and required to be stored at a temperature less than 45 degrees Fahrenheit in order to keep them fresh and keep for a longer period. Eggs are hatched with and have a protective coating, to ensure cleanliness, the eggs undergo a washing process but unfortunately that leaves them open to bacteria if left out of the refrigerator for a long period of time.

egg in pot

Q: Why does an egg float in water?

A: Even though the egg shell is hard, it continues to breath. A fresh egg will have limited space for air inside the shell, but over time the egg white and yolk shrink allowing for more air to build up inside the shell and this is why it is able to float in water.

Q: How to tell if an egg is hard boiled or raw?

A: Take the spin test. Take two eggs, one you know to be either fresh or hard boiled and the other you are not sure about. Spin both eggs at the same time, the egg that spins the fastest is the hard boiled egg. The reason is that the egg is solid inside and has a more fixed gravity, yet a uncooked fresh egg that is liquid will move as it is spun, slowing the speed down.

over cooked eggs

Q: Why do I have a grey ring around my egg?

A: The grey ring is from overcooking. The solution is to not leave the egg in the water for so long. Placing the cooked boiled egg in cold water or an ice bath, will stop the egg from continuing to cook after you remove it from the pot.

egg shell

Q: Is it better to peel eggs straight after you cook them or after they have been in the refrigerator for a while?

A: If you place eggs in an ice bath for about 5 minutes the egg white will shrink a little from the egg shell, making it easier to peel. It is the quick hot – cold reaction to the egg that helps the boiled egg peel easier. In contrast to the refrigerator, which is a slow cool, if you place hot eggs into the refrigerator and leave it there, the eggs are harder to peel when you take them out, say a few days later.

Q: Does altitude affect cooking time?

A: Adding salt may help to prevent the shell from cracking when boiling eggs.

cracked egg

Q: My egg cracked while it was boiling, should I throw it away?

A: The boiled egg is perfectly fine. You can use it in other recipes or eat it and there is nothing wrong with it. What happened is that the small air pocket in the egg, usually located at the large top end of the egg, expanded due to the heat, to the point that the pressure in the egg cracked the shell. Julia Child recommended piercing a small hole at the large top end before cooking. Here is the link to the page and video. Julia Child Straight Boiled Eggs and Coddling Method
