Separating Eggs
This requires no special equipment, just a bowl to crack the egg into, a little dexterity and maybe some practice. Some recipes call for either egg yolks only (homemade pudding) or egg whites only (sugar cookies; meringue) and some people with dietary restrictions may want to use only the egg white in recipes instead of whole eggs (sulfur sensitive people; people with high cholesterol).
Crack the egg as usual into a bowl, but don't open it all the way. After most of the white has come out, use one half of the shell as a "cup" to hold the yolk. You can get more egg white out by pouring the yolk back and forth a few times between the two shell halves -- carefully, though, so you don't pierce it.
If you are separating multiple eggs, a best practice is to have a small bowl for cracking the egg into and a larger bowl to collect up the egg whites. This way if you do have an OOPSIE and pierce one of the yolks, you haven't ruined six egg whites, just one.
