Thinking about this further. Placing eggs in water is essentially removing the oxygen from the eggs environment. I wonder if vacuum sealing eggs for the winter would have same effect.
Next dumb question. Can you freeze an egg
Discussion
It’s not just plain water. The pickling lime ( sodium silicate ) added to the water is what helps seal them as well. You can definitely freeze eggs. I’ve seen people crack them into ice trays and use them that way. I don’t do that a lot since freezer space is limited.
