How to hard-boil an egg

First, the right term is hard cook an egg..never hard boil. The white turns to rubber and you get the dark green sulfide ring which is prevented by being in cold water for 5 minutes after it is cooked.

Allow 2 cups of boiling water for first egg and 1 cup for each additional egg and place in top of a double boiler.

Ease in the eggs, set over boiling water, cover, remove from heat and let stand for 30 minutes.

Plunge into ice water for 5 minutes.

If you don't want to risk eggs cracking put into cold water. cover with 1 inch water, when water begins to bubble, remove from heat, cover pan and stand for 15-20 minutes...chill as above.

You can also bring eggs to room temperature to avoid cracking in the water,they don't like sudden temp. changes.
