The Sniff Test: Follow Your Nose

Your sense of smell is an unstoppable detector.  Crack the egg into a bowl and smell it.  An unpleasant or unusual smell? Head for the trash! The smell of a rotten egg is unique and easily recognizable.  Get into the habit of testing your eggs this way , especially if their expiration date has passed.

The consumption date: a reference but not a limit

Each carton of eggs has a  recommended consumption date (RCD) , often 28 days after laying. If this date has passed, don’t panic:  keep your eggs in the refrigerator , they can remain edible for several weeks.

The trick?  Combine this criterion with other tests, such as flotation or visual inspection, to avoid waste.

Visual inspection: a keen eye to spot anomalies

Make it a habit to inspect your eggs before cracking them:

  • A  cracked, sticky or powdery shell  indicates a problem.
  • Inside,  pink or black spots  are a sign of bacterial contamination.
  • A runny white or dull yolk does not guarantee a fresh egg, but it may still be edible if it smells normal.

The mirage technique: shedding light on freshness

Want to play detective?  Try candling!  Use a flashlight in a dark room to illuminate the inside of the egg.  If the air cell is small and the white and yolk seem firm , the egg is still fresh. Although more complex, this method remains fun and effective.

In conclusion

There’s more to egg freshness than just one method.  Combine tests for reliable results and avoid unnecessary waste.  With these tips, you’re ready to cook with confidence!
