1, when cooking eggs, you can use the method of delaying egg release, that is, after boiling water, put raw eggs into boiling water to cook, and the boiled eggs are easy to peel off their eggshells, because the eggs are composed of eggshells, inner and outer shell membranes, protein and yolk, and there is no gap between the egg membrane and protein. When raw eggs are boiled in boiling water, the eggshell with low temperature will expand rapidly after being heated, making the eggshell and egg membrane.

If you put a little salt in the egg, the boiled eggshell will be easily peeled off. Or soak the eggs in cold water and cook them in hot water, so that the eggshells will not break and will be easily peeled off.
