Can raw eggs be frozen? If raw eggs are nearing their expiry date, can they be preserved in the freezer? Would there be any issues with them after taking them out of the freezer?
You have two options for freezing egg whites: 


Use an ice tray and place one egg white in each of the wells
Gently mix the whites (don't whip) and place the mixture, either into ice trays or freezer bags.


Approximately 2 tablespoons of egg white mixture equals a single egg.
