Things you'll need:
A dozen eggs( or as many as you wish)
Water for boiling.
DirectionsHardboil your eggs normally.
When they are cool enough to handle, roll them around on a hard surface to crack them. Try not to break the membrane. Develop a nice overall cracked look.
Then re-boil in water with food coloring of your choice.
You could make AMAZING looking deviled eggs with these. , As well as try multi colored egg's cracking partially, reboiling in dye, cool, crack more and repeat the process.
