No-one likes to waste food so how can you tell if those eggs you bought weeks ago are still fresh? Egg farmers share these tips.

The easiest and the most obvious way is by the ‘best before date’ on the carton, which is why it’s best to store your eggs in the original carton. But there are other ways to determine the freshness of your eggs.

Eggs have a firm white, a small air cell at the wide end and a centred yolk.

A fresh egg will sink in water while an older egg will float. As an egg ages, the size of the air cell inside increases, causing it to float.

In a fresh egg, the yolk sits up high, and the white is thick and closely surrounds the yolk. An older egg has a flat yolk that breaks easily and a thin, watery white.

A cloudy egg white is a sign of freshness, not age. The cloudiness is the result of the high carbon dioxide content when the egg is laid.

And if you’re boiled some eggs but aren’t sure which is which.

To differentiate between a hard-boiled egg and a raw egg, simply spin it. A hard-boiled egg will spin longer than a raw egg. The liquid centre in a raw egg prevents it from building up enough momentum to keep turning.

Do you have any egg storage or cooking tips?
