Eggciting question!

[Liquiduk]

So I am at work tucking in to my tuna & egg salad for lunch when I notice my hard boiled eggs have grey rings around the yolk!

A quick google would suggest when boiled and left to cool naturally the grey ring around the yolk tends to happen but when plunged in to cold water to cool quicker the yolk stay yellow.

What do?

Ignore it or cool them in cold water?

boild, then run under cold water for a bit to stop the cooking process.
Nice yellow throughout yolks

I've always found grey colour and sulfur smell, is from overcooking them, people boiling them fir far to long, or when I forget.
Although I always run eggs under cold water to stop the cooking.

Its a reaction between the sulfur in the egg white and the iron in the yolk caused by overcooking

Don't overcook and cool under cold water should eliminate the grey ring

Surely the joy of a boiled egg lunch is the sulphorous leakage in the office afterwards.
