I prefer the jar method. I vacuum seal all eggs in jars. One trick to stay away from them freezer burning is to pour the excess juice in the bottom of the jar or container into the jar you will freeze them in. Remember the juices are made of water and water preserves the best in the freezer. Freezer burn is from air touching the eggs. I have eggs that I pulled out from 1997 that were still perfect. Also, mushiness comes from too much blood in the egg when curing them. Clean those eggs up and cure them as fresh as possible.
