Test Kitchen tip: Eggs separate more easily when cold, so if the recipe calls for separated eggs, do that when you take them out of the fridge, then let them come to room temperature. Here are three easy ways to separate an egg.
Egg temperature: It's easiest to separate eggs cleanly when they are refrigerator-cold. However egg whites whip up to a greater volume when they've had a chance to warm up a bit, 20 to 30 minutes. Before beating egg whites, always begin by separating the eggs.
Room temperature eggs are good for baking because they blend more evenly in batters and help the dough rise more easily than cold eggs straight out of the fridge. Cold eggs, on the other hand, can result in lumpy batter, a stodgy texture, and require longer baking times — and no one wants that!

Is it safe to keep eggs at room temperature? According to the FDA, eggs should be left at normal room temperature (68°F to 70°F) no more than two hours; or at higher temperatures no more than one hour.
Adding white vinegar or apple cider vinegar to your pot of water allegedly results in softer, easier-to-peel eggshells. That's because the acid in vinegar dissolves some of the calcium carbonate that makes up the egg's hard exterior.
Give Eggs Time To Cool
The quick cooling of the hard-boiled eggs causes the egg whites to contract, freeing them from the membrane. If you let them cool for about 15 minutes, the peeling is much easier.
There's plenty of methods for doing it, the most popular being old fashioned way of tipping the yolk between the two halves of the cracked egg shell until all the white has run into the bowl.
Partially spread the fingers of your dominant hand (not so much that your hand becomes stiff or overly splayed—just enough to let the egg white fall through), and, with your middle and ring finger, scoop the egg yolks up and out.
Use yolks soon after separating. Yolks can be kept covered in the refrigerator for a few days, but cover them with a bit of water before storing to prevent them from drying. Pour off the water before using. Egg whites can be refrigerated for a few days as well, but they can also be frozen.
Remember: Cold start = harder-to-peel eggs. It doesn't matter if it's in the oven or in a pot of water.
Apparently super fresh eggs are difficult to peel because the pH of the white is more acidic which causes it to adhere to the shell membrane more tightly. Two solutions here – use older eggs or add a little bicarb soda to the cooking water to increase the pH.
This is because the egg white or “albumen” in a fresh egg has a relatively low pH level, making it acidic. When cooked, these fresh egg whites bond strongly to the inner shell's membrane. As an egg ages, the pH level rises and the inner membrane is less likely to bond to the albumen, so the shell peels off much easier.
If you're still struggling, peel the eggs under cold running water, which will help separate the shell from the egg. For a more eco-friendly solution than keeping your tap running, you can just peel the eggs in a water bath. The water will have the same effect of slipping under the shell and helping dislodge the egg.
In most European countries, Salmonella is kept under control with preventative measures like vaccination. Farms are usually not allowed to wash eggs, so the cuticles remain intact, precluding refrigeration.
The eggs stored in cold temperature tend to undergo condensation when they are taken out to room temperature. This promotes the growth of bacteria over the egg shell, thereby contaminating the egg and making it harmful for human consumption.
If you're simply leaving them out on the counter, it'll depend on the ambient temperature of your room, but a general rule of thumb is to leave eggs out for at least 30 minutes if you're not using the water trick. If you're using the water trick (in a bowl of warm water), the eggs should be ready in 10-15 minutes.
