This may look like a regular, innocent egg… What you are about to see is eggs-actly what makes this tutorial so special!
Peel back the seemingly untouched shell to reveal a secret message on the surface of the hard-boiled egg.
Wonder how?The vinegar dissolves the calcium carbonate in the eggshell, allowing the alum to go through (or permeate) the shell and discolor the egg white. Mods on a boiled egg. Ingenious.
Thank you to Alberta Egg Producers.
