If you're beating the egg whites for meringue or a souffle, for example, even the tiniest bit of yolk in the white can cause them not to whip up nicely, so separating eggs is a skill you will want to master.
Using the freshest eggs you can find is a good start.
There is a membrane that encases the yolk which starts to break down as the egg ages, making the yolk more susceptible to breaking. So you have the best chance of successfully keeping the egg yolks intact if the eggs are very fresh when you separate them.
Cold eggs will separate better, so it's best to use eggs from the refrigerator not the kitchen counter. And of course you need to wash your hands thoroughly before starting, no matter which method you choose. And rinse your eggs under warm water to clean them as well.
Next, learning how to properly crack an egg is important. Eggs should always be cracked on a flat surface, never against the sharp edge of a counter or bowl. And lastly, have three bowls ready.
You'll need two medium or large bowls and one small bowl. The first larger bowl for your whites, the second larger bowl is for your yolks and the third small bowl is for the egg you're currently separating.
When you crack the egg, you let the white fall into the third (empty) bowl, then add the yolk to your bowl of yolks and discard the shell.
Only once you are sure your whites are free of yolk and pieces of eggshell, should you add the whites in the third bowl to the larger bowl of whites. Then repeat with your next egg.
Now for the methods to separate eggs.
7 Methods to Separate Eggs like a Pro
As far as methods for separating eggs, here are some that are tried-and-true:
Using the Egg Shell to Separate Eggs
This is probably the most common way to separate eggs. After giving the egg a firm rap on the counter in the middle (widest) part, trying to end up with two eggshell halves of equal size, and holding the egg over a bowl, carefully pry the two halves of the shell away from each other.
Let any egg white drip over the side of the shell half holding the yolk, and tip the egg white in the second half into the bowl as well.
Then transfer the egg yolk from one shell half to the other, tilting the eggshell halves slightly to let the egg white drip into the bowl.
Repeat several times until all that's left in the shell is the yolk. Add the yolk to your bowl of yolks and discard the shells.
Using your Fingers to Separate Eggs
This method is similar to the first, but in my opinion, not any easier and quite a bit messier! To use your fingers to separate eggs, crack the egg as described above, but then dump the contents into your palm, cupping your fingers and holding them slightly apart. Be sure to do this over your bowl!
Let the egg whites drip through your fingers into the bowl. When all that's left in your hand is the yolk, add that to your bowl of yolks.
The problem with this method, especially if you're going to be whipping your egg whites, is that even clean hands have oils on them, and that can interfere with your egg whites beating up into nice tall peaks.
Using an Egg Separator to Separate Eggs
For this method, you'll need a handy little gadget like the one pictured above to separate your eggs. Egg separators work really well, it's just a question of whether or not you want or need yet another kitchen gadget.
But egg separators aren't expensive and you can find a more traditional style like this or go with this clever design that allows you to separate two eggs at once.
Using the same method described above to crack your egg, you will then drop the contents into the separator and let it do its thing. Easy peasy.

How to Remove Egg Shell from the Egg Whites
Other methods include using the tine of a fork or a moistened finger, or even a finger you've rubbed on a sliced garlic clove, but hands down, the egg shell is the best way to remove a small piece of eggshell.
