One accurate method to check whether eggs are still fresh before using them is to see if the egg floats in water. If it does, it should not be eaten. Eggs are sometimes still fresh a few days after their expiration date, so it is best to check before discarding them.
Since eggs are porous, they will take in air through their shells and over time their shelf life decreases. This method of testing is quick and easy.
- Place egg in water
- Watch how the egg reacts
Place the egg in a bowl of water.
If the egg is lying on its side at the bottom of the bowl, it is still considered fresh. If it is upright, it should be eaten within a few days or hard boiled. If the egg floats at the top, it should be discarded.
