Well, the first rule is NEVER boil eggs. They should be called Hard Cooked Eggs. Boiled eggs can be rubbery and hard to peel but this is a simple method I have used forever and I never have a problem with the yolk looking green or the shells sticking. Make sure your eggs are at least 5 days old so the shells remove easily. Hope you try this! It has worked for me for almost 50 years.
