FOund some helpful hints & thought to share!!
AT LEAST A WEEK OLD: Extremely fresh eggs are not recommended when making hardboiled eggs. They are very difficult to peel. Hard-boiling is the best use for eggs nearing their expiration date. PRICK THE SHELL: Carefully push a needle or pushpin into the large end of the uncooked egg, about 1/4 inch. This will pierce the tiny air bubble (it is present in every egg) that in an unpricked egg expands and, as the egg is heated, cracks the shell. A tiny hole allows the air to escape.
SIMMER METHOD: Bring a pot of water to boil. Lower the chilled eggs into the boiling water and bring the water back to a simmer and set the timer: 11 minutes for medium eggs, 12 minutes for large eggs and 13 minutes for extra large ones. Keep the water at a low simmer that produces small bubbles and a very slight movement among the eggs.
CODDLE METHOD: Some great cooks prefer to coddle eggs rather than simmer because the results are more reliable. Place the chilled eggs in a pot of cold water (6 cups for 1 to 4 eggs and an additional cup for each additional egg). Bring the water to a full-rolling boil; remove from heat and cover. Set the timer for exactly 17 minutes (or 18 for jumbo or extra large eggs).
NO MORE UGLY GREEN RING: Sulfur in eggs can cause a greenish grey film to form on the surface of the yolk when the temperature of the yolk exceeds 158 F. This discoloration is not unhealthful. The change of color occurs when eggs are allowed to remain warm after proper cooking. To prevent this, immediately transfer the cooked eggs to a bowl of ice water. The sulfur in the eggs moves away from heat allowing you to discard it with the shell.
FOOLPROOF PEELING OF HARD-COOKED EGGS: Tap the egg gently to break the shell in many places all around the egg. Start peeling the egg by first placing it under a small stream of cold water and begin removing the shell from the large bottom-side. If the shell is resistant and wants to take part of the white with it, simply drop the egg into boiling water, wait 10 seconds and immediately transfer it to ice water. This will expand and contract the shell quickly and will release the shell easily.
STORE COOKED EGGS PROPERLY: Cooked eggs should be submerged in cold water in an uncovered container and stored in the refrigerator. They will keep for several days this way without loss of flavor, nutrition or texture.
