As the cooked egg white cools, it begins to stick to the shell's innermost membrane. Two other egg-peeling tips are to start at the larger end (the one with the air pocket) and, if the shell is giving you a difficult time, to remove it under cold running tap water. If you want to slice the egg, chill the whole peeled egg in the refrigerator for at least 15 minutes. By so doing, the yolk is less likely to crumble or break away from the white.
