To make the perfect hard-boiled eggs, put eggs into the a large sauce pan and cover with water. (Make sure there is about an 1" to 1 1/2" of water above the eggs). Keep pan uncovered and bring water to a rolling boil, then immediately reduce the heat to a simmer and set a timer for 12 minutes. After 12 minutes, transfer the eggs to a bowl full of ice water for about 5-10 minutes before peeling.
