If you’re wondering if this stain is a sign of aging, the answer is no. It’s not an indicator of freshness. To determine if an egg is still good, you can use the glass of water test (if it stays at the bottom, it’s fresh; if it floats, avoid eating it) or simply check the best-before date on the carton. Easy, right?
And what about the taste?
Worried that red dot might affect the taste of your food? Don’t worry, you won’t notice any difference. Whether it’s an omelet, a cake, or scrambled eggs, the taste remains perfectly identical. No strange flavors to report , and no abnormal texture either. You can cook with peace of mind.
Can we avoid these eggs?
Some brands screen their eggs with special lamps to detect and discard those with small visual anomalies , such as these famous spots. As a result, there are fewer of these in industrial eggs than in eggs from farms or small producers. But even then, it’s only a question of appearance, not quality.
Bonus tip: What to do if the stain bothers you?

If this little trace really puts you off, you can simply remove it delicately with the tip of a knife or a spoon before cooking. And presto, no one will see it!
A small red spot doesn’t detract from the quality of your egg, so there’s no need to worry.
