Determining if an uncracked egg has gone bad involves a simple egg freshness test. Here's how you can check the freshness of an uncracked egg:
Look at the Date: If you purchased the eggs from a store, check the "sell-by" or "expiration" date on the carton. Use the eggs before this date for the best quality.
The Float Test: This is a popular method to check egg freshness. Fill a bowl or glass with cold water and gently place the egg into the water.
- Fresh Eggs: A fresh egg will sink to the bottom and lie horizontally on its side.
- Less Fresh: An older but still edible egg may stand upright on the bottom.
- Questionable: If the egg stands on its end but remains at the bottom, it's less fresh and best used for cooking rather than consuming raw.
- Spoiled: If the egg floats to the surface and doesn't touch the bottom at all, it has likely spoiled and should be discarded.
Smell Test: If you are uncertain about an egg's freshness after the float test, you can do a smell test. A spoiled egg will have a distinct unpleasant smell, similar to sulfur or rotten eggs. Fresh eggs should not have any noticeable odor.
Crack Test: If you are still unsure about the egg's freshness after the previous tests, you can crack the egg onto a plate or into a bowl. A fresh egg will have a well-defined yolk that sits high, and the egg white should be clear and slightly thick. On the other hand, a bad egg will have an off-smell, and the yolk may break easily or appear flattened, and the egg white may be watery.
Remember that proper egg storage is crucial for maintaining freshness. Store eggs in their original carton in the refrigerator and use them within a reasonable time frame. If you have any doubts about an egg's freshness, it's best to err on the side of caution and discard it. Consuming spoiled eggs can lead to foodborne illnesses and should be avoided.
