Technique for hard-boiled eggs:
Choose the right size pot to cook your eggs in: The eggs must not be stacked but be in one (1) layer only. Gently place the eggs in a single layer in a pan with enough cold water to cover eggs completely (approximately by 1 inch of water over the top of the eggs).
Too much water will take too long for the water to get boiling, which can throw off the timing and give you overcooked eggs. Too little water causes parts of the eggs to be exposed and end up undercooked.
If you have 2 or 3 layers of eggs stacked up in a small pot, they may cook unevenly. Use a large pan and limit cooking to two (2) dozen eggs at a time only.
Over high heat, bring water JUST to a rapid boil.
As soon as the water reaches a rapid boil, remove pan from heat and cover egg pan tightly with a lid.
Set timer for 17 minutes for large eggs or 20 minutes for jumbo eggs.
After 17 or 20 minutes (depending on size of your eggs), remove lid and drain off water from the eggs.
Watch the time when cooking the eggs carefully. Overcook causes a green layer to form around the yolk. This layer is caused by a reaction between the iron in the yolk and the sulfur in the white. Heat speeds up this reaction, so the longer your eggs cook, the greater the chance of discoloration.
Stop the cooking process: Transfer the eggs to the bowl of ice cubes and/or cold water. NOTE: While they're in the cold water, a layer of steam develops between the shell and the egg white. The steam helps make peeling an egg much easier.
Let eggs cool at least 10 minutes in cold water, then drain. Either store in refrigerator or peel the eggs (see below for How To Peel Hard-Cooked Eggs Easily).
A quick test to ensure that your eggs are hardboiled: When eggs have cooled, spin them on a hard surface (just like you would spin a top). If the eggs spins quickly without taking off or flying off in one direction, the egg is hard boiled and finished. Undercooked eggs (or uncooked eggs) will have a wobbly and unsteady spin.
