Hard Boiling Eggs....

I'm hoping to dye some Easter eggs with Ellie today or tomorrow. In preparation, I am hard boiling eggs. Suddenly it occurs to me that I don't really hard boil eggs very often. Rarely, in fact. And I can't remember how to do it. So I'm trying a method I've never done before. I found it on WikiHow and thought I'd give it a shot. Have any of you used this method before? In about 10 minutes we'll see how well it works...

From WikiHow:

(Note: this method consistently produces a perfectly-cooked egg with lovely, all-yellow yolks--no more green-gray rings!)

1. Place the raw, uncracked eggs in a pot. Fill the pot with enough cold tap water to completely cover eggs with about 1 inch of water over them. Add plenty of salt to make the egg easy to peel later.
2. Bring to a rolling boil on high heat. Once the water is brought to a good boil, promptly cover the pot and turn off the heat {the retained heat in the water and pot will continue to gently cook the eggs without overcooking them and discoloring the yolks}.
3. For hard-boiled, leave the eggs in the water for 15 minutes; for soft-boiled, leave them in no longer than 10 minutes.
4. Remove from heat and immediately chill the eggs by placing them under cold running water or in a bowl of ice water to stop the cooking process. Chill for a few minutes until the egg is completely cooled.
5. To peel, crack the shell around the entire egg and remove.

EDITED: Well, no cracked shells, and I boiled 10 of them, so that's got to be a good sign!
