Why does the eggshell stick to the hard boiled egg sometime and other times slips right off?

Question

This is a mystery I would like to solve.

Answer 1

The fresher the egg the more it sticks, those who slip off easy are older. Learned a trick to get even fresh eggs off easy.
When you are boiling them add a tablespoon or just a dab of vinegar. Causes the shell to slip off easy.

Answer 3

I made devil eggs for easter and my sister and I always boil and chill them the night before then before the ham is done we put them in a bowl of warm water and tap them lightly with a spoon just enough to crack the shell but not break the egg then we just peel off the shell in the water of course we sometimes ruin some but i would suggest start peeling from the bottom of the egg you know the somewhat flat side it's has an air pocket there and you can go from the bottom up

Answer 4

Here is the way I have done it and works quite well although not always. Add a little vinegar and some salt to boiling water and boil the eggs for ten minutes. Immediately remove from the heat and run under cold running water until the eggs feel cool and then pop them into the fridge for an hour and they should peel nicely.

Answer 5

Because eggs put up a tough fight to keep the color out.

First, some hard-boiled facts. Baby chicks come from fertilized eggs. (But don't worry -- eggs you buy in the grocery store aren't fertilized.) Everything about an egg is designed to protect the growing chick.

The next time you peel a hard-boiled egg, look closely at the shell. That filmy skin between the shell and the egg -- the one that sticks to the shell as you peel it off -- is the baby chick's first layer of protection.

There's another filmy membrane next to the egg's white part, and there's a thicker membrane around the yolk. All these barriers work as an umbrella to protect the chick from bacteria and other organisms. (An eggshell has more than 6,000 pores that microscopic bugs can get through!)

Dyes -- like food coloring or natural colorings from plants -- all work basically the same way. Their colored molecules hook up with molecules of the material to change its color.

If the inside is colored, it could be because of a crack in the shell. Or if your dyed water is colder than the egg, the color has a better chance to sneak inside. But if it all goes right, dyes normally don't color the hard-boiled whites -- the shell membrane works hard to prevent the color from soaking through!

Answer 6

You have to lrt the egg cool compleatly to get the shell of easily .Try adding salt to the water while boiling ,Then when their done put them in water with a few ice cubes the will crack on their own and peel perfectly. but the answer is they are still hot inside and just like noodles which are made with egg ,when hot it sticks to anything.

Answer 7

The shell sticks to the fresher egg. In older eggs, the shell comes off easily.

Answer 8

The fresher the egg the more it sticks. If you dont' want the shell to stick use eggs that have been in your fridge for at least 3 days.

Answer 9

i'm not sure, but if you add about a tablespoon of salt to the water when you are boiling the eggs, they will peel super easy and the shell won't stick.

Answer 10

Vinegar added to the boiling water will cause shell to slip off.
