John Coffer claims that your albumen solution can be made up and frozen until your ready to use. He claims this doesn't have any adverse effects. We have a local farm that raises free range eggs and these are truly free range and not what the poultry industry claims to be free range. I started buying from them for making albumen but now we buy all our eggs for consumption and our chicken also from them. If you read the reports about free range eggs you'll see how much more healthy they are for you. Of course the cheesecake made from all the yolks don't help the waistline much but it sure is tasty.
