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.
A boiling start for 30 seconds to a very gentle simmer for 13 minutes, then an ice bath at the end makes perfect, easy-to-peel hard-boiled eggs.
Here's her hack for how to peel hard-boiled eggs in large batches: Put five thoroughly cooled hard-boiled eggs into a small plastic container with some cold water, top with the lid and then gently rock and shake until the shells break and fall away. You'll almost always end up with perfectly peeled eggs.
Shocking your recently boiled eggs by submerging them into a bowl of ice water is key. 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.
Some people prefer to peel their hard-boiled eggs before storing – and that's A-OK. You'll just need to take a few extra steps: Transfer hard-boiled eggs to a bowl of cold water immediately after cooking to help them cool down faster. Peel the eggs under running water.
A soft boiled egg is boiled for a shorter amount of time, typically 4-6 minutes, so that the yolk remains runny while the white is only partially set. A hard boiled egg is boiled for a longer amount of time, typically 10-12 minutes, so that both the yolk and white are fully cooked and solid.
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.
While overcooking hard-boiled eggs does have its obvious drawbacks — rubbery dry whites and pale crumbly yolks — it actually does make them easier to peel. That's because one of the determining factors in peel-ability is the pH of the egg — the higher (less acid), the easier.
Give the eggs at least five minutes in the ice bath before you try to peel them—letting them cool may help make it easier to peel them, but it's also so you don't burn your hands.
Place the pot over medium-high heat, without a lid, and allow it to come to a rolling boil, which is indicated by large, vigorous bubbles. Bringing the pot to a boil without a lid will slow down the heating process and reduce the likelihood of the shells cracking.
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.
When you plunge the eggs into a bowl of ice and water, the shock of the cold water stops the cooking process, preventing them from overcooking, explains The Spruce Eats. Otherwise, the residual heat in the eggs will continue to cook them, even after they have been removed from the source of heat.
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.
Boil for 6 – 7 minutes over medium-high heat for perfect hard-boiled eggs. Using a slotted spoon, transfer them to a large bowl of ice water and let them cool for a few minutes. Or you can place them under cool running water to stop the cooking.
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.
The vinegar in the water makes the eggs easier to peel. Here's why: The vinegar's acid not only dissolves some of the calcium carbonate in the shell, it also helps the whites set faster. Running the hard-boiled eggs under cold running water as you're peeling, meanwhile, helps the shell separate from the membrane.
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.
For maximum freshness, leave them in their shells until you are ready to eat or prepare. The shell will help to protect the egg from bacteria, and can help prevent them from absorbing odors from other foods in your refrigerator.
It's best to store hard-boiled eggs with the shells on, as the outer layer serves as a protective barrier. Plus, they're easier to peel once they've chilled in the fridge for a while. It's a win-win! Transfer hard-boiled eggs to a bowl of cold water immediately after cooking to help them cool down faster.
