Whether hard- or soft-cooked, this method is incorrectly called boiled eggs. Although the cooking water must come to a boil, eggs should NOT be boiled because high temperatures make them tough and rubbery.
A greenish-gray ring may appear around a hard-cooked egg yolk. It's unsightly, but harmless. The ring is caused by a chemical reaction involving sulfur (from the egg white) and iron (from the egg yolk), which naturally react to form ferrous sulfide at the surface of the yolk. The reaction is usually caused by overcooking, but can also be caused by a high amount of iron in the cooking water.
Eliminate the ring by avoiding overcooking and by cooling the eggs quickly after cooking. Run cold water over the just-cooked eggs or place them in ice water (not standing in water) until they have completely cooled. Then refrigerate the eggs in their shells until you're ready to use them. Hard-cooked eggs in the shell can be refrigerated up to one week.
Peeling Hard-Cooked Eggs:
Keep in mind that the fresher the egg, the harder it is to peel. Try to buy your eggs a week to 10
days in advance of cooking them. Fresh eggs are more difficult to peel after hard-cooking. The
air cell that forms between the shell membranes as the egg ages helps to separate the shell from
the egg. Some new research suggests that yolk centering may be better if eggs are stored small-
end up for 24 hours before hard-cooking. Piercing the shell BEFORE cooking may also make
peeling easier.
Remove the shell after the eggs are cool. Thoroughly crackle the shell all over by tapping gently on a table or counter top. Then roll the egg between your hands to loosen the shell. Start at the large end and peel off the shell. Hold egg under running cold water or dip in a bowl of water to help ease off the shell.

Try a method of no muss or fuss with deviled eggs that is so simple, even beginning
cooks can master it easily. To tote deviled eggs to a picnic or tailgate party, place all
ingredients for the deviled eggs in a sealed food storage bag. Place egg whites in a
separate sealed container. Knead all the filling ingredients until smooth and well
blended. Transport on ice or coolant in a cooler, along with the egg whites, and
assemble on the spot. Simply snip off a corner of the bag with a scissors and squeeze
to refill the whites, just as if you were using a pastry bag.
