How to make a Hard Boiled Egg

Lay eggs on bottom of the pot.
Try not to stack your eggs (it's better to do it in batches than overfill your pot).
Fill with water so it's an inch over the eggs.
Put on high heat and bring to a rapid boil.
Let boil for 12 minutes.
Remove from heat.
Remove the eggs immediately from the pot (I use a slotted spoon) and plunge them into cold water until you can pick them out of the water without burning your hands (a bit under a minute)
