One of the staples of the office lunchbox is the hard-boiled egg. A single large egg contains iron, protein, vitamins and minerals, with just 70 calories. The problem with hard-boiled eggs, however, is that they can be difficult to peel because pieces of the shell often stick to the surface. With the right techniques, however, a pleasant midday meal won't turn into a frustrating activity.
Avoid the pitfalls associated with breaking the shell in one spot and then picking away at the shell as you work around the egg. If you do that, white pieces of the egg may come off with the shell pieces.
Place the egg onto a paper towel or napkin. Knock something hard against the egg to break the shell and then roll it on a hard surface, applying enough pressure so that you hear a crackling sound.
Grab a loose section of shell at the larger end once the egg is sufficiently cracked and carefully peel the shell cleanly away from the egg white. Sometimes you can do this in one long piece.
Practice the technique a few times, learning how much pressure is needed to evenly crack the egg's shell all the way around.
