Fill a glass or container with cold water to three-quarters of its capacity.
Carefully place the egg in the water to observe its behavior:
If the egg floats completely on the surface: The egg is spoiled and should be discarded. This occurs because the air accumulated inside the shell makes it float.
If the egg is kept tilted in the water: It means that the egg is old, but it is still safe to consume, although its quality will not be optimal.
If the egg sinks and lies on the bottom: The egg is fresh and ready to use in your recipes.
Councils:
Check the peel: In addition to the water test, check that the shell is clean and free of cracks. Eggs with damaged shells are at higher risk of being contaminated.
Smell as a last resort: If an egg floats but you’re not sure, crack the shell into a separate container. If it has an unpleasant smell, discard it immediately.
Store properly: Store eggs in the refrigerator to prolong their freshness. Place them on the main shelf, not on the door, as temperatures are more stable.
Use old eggs for certain recipes: Although older eggs aren’t ideal for stir-fries or omelets, they work well in recipes where they’re mixed with other ingredients, such as biscuits or cakes.
