Unless you have a direct and reliable source for eggs, it is often hard to tell when your eggs were actually laid. Store-bought eggs usually have “best by” dates listed on their cartons, and although that date can give a clue as to freshness, it ultimately is not a sure sign of whether or not an egg is still good to eat. However, there is an easy kitchen hack that will tell you in just seconds whether your eggs have gone bad.
Place your eggs in a bowl of water filled to the top. If an egg lies on its side on the bottom of the bowl, it’s still fresh. If it sits upright but is still resting on the bottom of the bowl, your egg is on the older side but still good to go — perfect for hard boiling and peeling. If the egg floats, however, there is a good chance it may be expired.
