An egg can float in water when its air cell has enlarged sufficiently to keep it buoyant. This means the egg is old, but it may be perfectly safe to use. Crack the egg into a bowl and examine it for an off-odor or unusable appearance before deciding to use or discard it.
An egg that floats in water is no longer fresh but may still be safe to eat, according to the USDA.2 Crack the egg into a bowl and observe if it has an off-odor or looks discolored or out-of-the ordinary, in which case you should throw it out.
To conduct a float test, fill a bowl or cup with water (it should be big enough to fully submerge your egg). Gently place your egg inside and see if it sinks or floats. If it floats, it's old and you may want to toss it.
After trying several methods to determine if an egg is cooked or not, there were a few that came out on top. Contrary to what you might have heard, hard-boiled eggs do not float—but they do act differently when you spin them or shine a flashlight through them.
Very fresh eggs will sink to the bottom and lay on their sides. If an egg stays at the bottom but stands on its small end, it's still acceptable to eat; just not quite as fresh. These "more mature" eggs are no less nutritious than a fresher egg, and most people are unlikely to notice a difference in taste.

Lower the heat slightly – so the eggs don't crack due to being bashed around but water is still at a gentle boil. Start the timer – 6 minutes for runny yolks, 8 minutes for soft boiled, 10 minutes for classic hard boiled, 15 minutes for unpleasant rubbery whites and powdery dry yolks.
People add salt to a pot of water before boiling eggs for a few reasons. First, salt helps water reach its boiling point faster, which means the eggs boil at a higher temperature. Second, salt helps seal cracks that may develop as eggs bounce around in bubbling water.
Information. Eggs may be refrigerated three to five weeks from the day they are placed in the refrigerator. The "Sell-By" date will usually expire during that length of time, but the eggs will be perfectly safe to use. Always purchase eggs before the "Sell-By" or EXP (expiration) date on the carton.
In the United States, fresh eggs sold in stores are required to be washed and refrigerated, and then need to stay refrigerated. If you raise hens in your backyard, freshly laid eggs can be kept at room temperature, but if you wash them, you should refrigerate them.
The rule of thumb? You can leave eggs on the counter about two hours at room temperature or one hour if the temperature is 90 degrees or hotter before you start to worry, per the Egg Safety Center. After two hours, you'd be safer to throw those eggs out and get a fresh dozen rather than chance it.
Place your eggs in the water. If your eggs sink to the bottom and lie flat on their sides, they are very fresh. If your eggs stand on one end at the bottom, they are a few weeks old, but still fine to eat. If your eggs float to the surface, they are no longer fresh.
On those egg cartons, if an expiration date appears, it can be no more than 30 days after the pack date. "As long as they're kept properly refrigerated at 40°F or lower, fresh eggs are safe to eat four to five weeks beyond the carton's Julian date," Maloberti says.
When you crack it open, look for other signs of discoloration or a sour smell. A fresh egg doesn't have a smell, but an egg that is going bad smells like sulfur. If you smell something, chances are, the egg is no longer good.
As with raw eggs, hard-boiled eggs last longest when stored in the refrigerator. According to The American Egg Board, hard-boiled eggs, still in their shell or peeled, will remain tasty for about a week when properly stored (which means in a fridge that is no warmer than 40°F).
The color of the yolk will change based on the diet of the hen who laid it, so the shade of yellow or orange nothing to do with freshness. Instead, inspect the egg white, or albumen. If it is pink, green, or iridescent, the egg has been contaminated by Pseudomonas bacteria and is not safe to eat.
Overcooked eggs will result in a very hard yolk and sometimes a green ring around the yolk. They will also have a slightly unpleasant sulfur smell after sitting in the fridge. I recommend cooking them for no longer than 12 minutes and transferring them to a large bowl of ice water as soon as they are done cooking.
Allow the eggs to sit in the hot water for the following times according to the desired doneness: 3 minutes for SOFT boiled; 6 minutes for MEDIUM boiled; 12 minutes for HARD boiled. Prepare a bowl of ice water. Transfer the cooked eggs to the ice water to cool completely before peeling.
For one to four eggs, bring the water to a rolling boil, cover the pot, and turn the heat down to its lowest setting for 12-14 minutes. For five to eight eggs, cook for 15 to 18 minutes. For nine to one dozen eggs, cook for 20 minutes. After cooking, transfer the eggs to a bowl of ice water.
According to the USDA Food Safety and Inspection Service (FSIS), you can freeze eggs for up to one year. When you're ready to use frozen eggs, thaw them overnight in the refrigerator or under running cold water. Use egg yolks or whole eggs as soon as they're thawed.
Although cooked eggs can be a nutritious treat for your dog, raw eggs are dangerous. As with humans, raw eggs can expose dogs to harmful salmonella, which can then spread back to their pet parents (especially those with a compromised immune system).
Place eggs in a medium pot and cover with cold water by 1 inch. Bring to a boil, then cover the pot and turn off the heat. Let the eggs cook, covered, for 9 to 12 minutes, depending on your desired done-ness (see photo).
