Eggs have an air cell that becomes larger as the egg ages and acts as a buoyancy aid. An egg can float in water when its air cell has enlarged sufficiently to keep it buoyant. This means the egg is older, but it may be perfectly safe to use.
Is it OK to boil eggs that float?
If the egg sinks or stays at the bottom, it is still fresh. An older egg will either stand on its end or float. The float test works because air builds up inside the egg as it ages, and this increases its buoyancy. However, an egg that floats may still be safe to eat.
Is it OK to eat floating eggs?
If they sink to the bottom and lay flat on one side, they are fresh and good to eat. A bad egg will float because of the large air cell that forms at its base. Any floating eggs should be thrown out.
Why are my eggs floating in boiling water?
Why Do Cracked Eggs Float? If the egg’s shell is cracked, egg white will leak out into the boiling water. This reduces the mass of the egg, making it easier for the less-dense egg to float. Some bits of boiled egg white will float around in the saucepan of boiling water, which is unattractive but harmless.
How can you tell if an egg is bad when boiling?
Fill a bowl with water, and carefully place an egg on top. If the egg sinks like a stone, laying down on its side, it’s still very fresh! If it sinks but doesn’t lay flat — and instead it kind of stands up, wobbling — your egg is OK and probably just right for hard-boiling.
How long should eggs boil?
As soon as the water begins to boil, turn off the heat and cover the pot. Leave the eggs in the hot water for anywhere from 10-12 minutes, depending on how you like your eggs. The 10-minute eggs will have vibrant, creamy yolks, while the 12-minute yolks will be paler and opaque, with a chalkier texture.
