Doctors Reveal What Really Happens When You Eat Boiled Eggs Every Morning… See More

1. Check the Egg Before Boiling
The first step in preventing problems is to examine the egg before you cook it. One of the most reliable methods is the water test. Fill a bowl with cold water and gently place the egg inside.

If the egg sinks and lies flat on the bottom, it is fresh.
If it sinks but stands upright, it is older but still safe to eat soon.
If it floats to the surface, it has likely gone bad and should be discarded.
Eggs float because, over time, moisture and carbon dioxide escape through the shell, allowing air to enter. The larger the air pocket inside, the more buoyant the egg becomes.
