Fact 6: How hard an egg is to peel can indicate its freshness
Fresh eggs tend to be harder to peel because the egg white sticks tightly to the inner shell membrane. As eggs age, their acidity decreases, allowing the white to separate more easily from the shell. Letting eggs sit in the refrigerator for one to two weeks before boiling can noticeably improve peeling results.
Fact 7: Hard-boiled eggs have a shorter shelf life than raw eggs
While raw eggs can usually be stored safely in the refrigerator for three to five weeks, hard-boiled eggs don’t last nearly as long. Once cooked, they should be eaten within about one week when properly refrigerated to maintain safety and freshness.
