Ideally, peel the eggs as soon as they're cool. Start at the broad end, and hold the egg under running water to loosen any bits of stubborn shell clinging to the sides. Another thing to keep in mind is the freshness of your eggs.
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.
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.
We find the time saved by not tempering the eggs worth the gamble. 2. Drop the eggs into boiling water. Eggs that are added to a pot of boiling water rather than brought to a boil along with the cold water in the pot will be easier to peel.
Remember: Cold start = harder-to-peel eggs. It doesn't matter if it's in the oven or in a pot of water.
The fresher the eggs, the harder they are to peel. 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.
The most important step to getting a perfect, pock-free peel is to tap your hard-boiled eggs with a spoon or roll them on the countertop to crack the shells before you shock the eggs in cold water. This will loosen the membrane and make them easier to peel.
Leave eggs in the ice bath for 10+ minutes to allow for thorough cooling/easy peeling (you can place them under running cold water instead, but without the cold shock from the ice bath, you may have a harder time peeling, especially if your eggs are farm fresh like ours).
To avoid getting a green yolk, cook your eggs just long enough to reach the desired doneness—no more. And quickly plunge the cooked eggs into cold water to stop the cooking process and minimize the iron-sulfur reaction. Some people also say that the cold-water plunge makes eggs easier to peel.
