You can just use the whites of the egg and throw the yolk away. I just crack the egg and keep dumping it back and forth between the two shells until only the yolk is left in the shells and the white is in the bowl. Does that make sense?? lol. I could show you a lot better..

It is kinda hard to explain on here.
Just remember that when you crack the egg... don't let the yolk fall into the bowl. Just the white part.
