Eggs need to be room temperature (or as close to it as possible)
1. Fill a sauce pan with water 3/4 full 2. Add a dash of salt to increase boil 3. When water is boiling and bubbling, add eggs one at a time carefully (I use a wooden spoon to dip the eggs in with) 4. Let boil for exactly 10 minutes 5. Separate water from eggs and let eggs cool on their own in the room temperature air until they are fully cool. DO NOT run under cold water as shells may break and yolk will not set correctly. 6. Mark hard-boiled eggs so that they aren't mistaken for normal eggs
Quick Egg Fact: The cholestrol in eggs is actually not that bad for you, but yolk is what carries most of the calories in an egg. The egg white is mostly all protein. One egg white is only 17 calories where as a yolk alone is nearly 55 calories.
