These eggs should be "hard-cooked" in hot water

When you’re celebrating Pesach one thing is certain, there will be eggs involved.  Some will get broken, others will be incorporated into myriads of “family favorite” recipes and others, those special few that are chosen, will be hard cooked. According to the American Egg Board, the terms “hard-boiled” is a misnomer because you really don’t want to boil your eggs (it makes them tough and rubbery). Instead, these eggs should be “hard-cooked” in hot water.
What, you ask is the difference? Well, when you cook the egg at a constant boiling temperature the continual heat overcooks the proteins in the egg, leaving the white tough and rubbery. Overcooking can also cause a greenish black icky looking film to form between the yolk and the white. Bringing the water with the eggs in them to a boil, then removing the pan from the heat and letting the eggs sit in the hot water for 20 minutes allows them to cook slowly and consistently. The Egg Board has great instructions that I have taken the liberty of modifying:
First, don’t add salt to the water. Use room temperature eggs, they’re much less likely to crack in the hot water. An egg that is at room temperature at the start of cooking requires approx. one minute less time to cook than eggs plucked from the refrigerator and placed right into the pan.
Place your eggs in a saucepan, making sure that you don’t overcrowd them (no stacking!). Cover them with cold water, bring to a boil, let boil for approx. one minute and then remove from the heat. Cover the pan with a lid and let the eggs stand in the water for approx. 12 minutes for medium sized eggs; 15 for large eggs; 18 for extra large eggs. Drain the water and then submerge them in ice-cold water for a few minutes. Peel immediately if you need them or keep them refrigerated for up to 5 days. Hard-cooked eggs are easiest to peel right after cooling. Once you peel them, they should be eaten as soon as possible.
Note:  Never EVER microwave eggs – trust me, they will explode.
