Testing old eggs
QI have some new hens that are roughly five months old. They started laying a couple of weeks ago, or so I thought until I stumbled upon a stash of 20 eggs in the corner of the garden. Can I still eat the eggs or should I throw them away?
AJullie Moore says: To see whether an egg is still viable to eat, you can perform the ‘float test’.
Simply fill a clean, clear glass with warm water and gently drop the egg in. Fresh eggs will sink and sit horizontally on the bottom. As an egg ages, the air pocket inside the egg enlarges — this will cause one end of the egg to rise in the water. As long as one end of the egg touches the bottom, it’s still good to eat. Floating eggs are very old and are likely to have gone off — try shaking the egg, if you hear the contents sloshing around, it’s bad or crack the egg into a bowl to smell and see. But if there’s any doubt, throw it out!
Remember, if you do a float test, you should use the egg straight away (if it’s viable) as the bloom (a thin, almost transparent protective coating put down
by the hen just before an egg is laid) will have been washed off.
Good eggs will sink, bad ones will float
