Does shelling hard boiled eggs reduce their post-cooking shelf life - bother in terms of quality and food safety? If I make, say, a dozen eggs to keep in the fridge for a week or so, should I peel, not peel, or does it not matter?
Definitely in the shell, and not in water. They can last close to a week that way. Do not be tempted to peel and cover in water. They will be foul in a couple of days. Possibly peeled would keep in acidulated water but I have not tried that.
