Hard cooked eggs

I had read somewhere that if you salt the water used for boiling eggs, it will keep the shells from cracking. Hmmm...okay I have tried it a few times and have had no cracked shells. I did it again yesterday to show my hubby my new trick. Again, success!
However, it would have been much more impressive if I'd remembered to set the timer and the eggs weren't overcooked lol. Oh well, we ate them anyway.
Try it and let me know if salting the water works for you too!
