Can you crack it? Science reveals the best way to peel a boiled egg

Egg peeling can be a frustrating experience for anyone who’s ever tried it, but with scientific insights, you can make it easier. Older eggs are less sticky due to an increased air cell and higher pH in their shell membrane, making them more pliable as they age. Proper boiling techniques—using hot water first to relax the membrane bonds followed by cooling in ice water—can help achieve a smoother peel while preventing cracking. Additionally, alternative methods like steaming or air-frying may offer improved results with further study, and once peeled, eggshells have innovative uses beyond disposal, such as composting or biomedical applications.
