Fresh eggs are known to be more difficult to peel, as fresher egg whites tend to stick to the membrane on the inner shell. As eggs age, the acidity decreases, allowing for easier separation of the egg white from the shell. For an easier peeling experience, let your eggs sit in the refrigerator for a week or two before boiling. (4)

Fact 7: Their shelf-life may not be as long as you think
