Use Cracked Eggs
If you've accidentally cracked an egg, you can still use it later -- just pour the egg into a container, seal, and store in the refrigerator for up to four days. But if you purchased eggs that were already cracked, do not use them; throw them away. Separated egg whites can be safely frozen for a year, but separated egg yolks can not be frozen. You can freeze whole eggs by beating the egg whites and yolks together and freezing in a sealed container -- these will also last for up to one year.
