An important question about eggs

[Sittingduck]

Specifically egg yolks, actually.

Why has the perimeter of the yolk gone blue/grey in colour? Does this mean the eggs are off (well within use by date). This happened with some hard boiled ones!




Thanks in advance

over-boiled

or/and not cooled quickly enough....

Sort of.

To avoid a grey edge on a hard boiled egg, cool it quickly under running cold water when you take it off the heat. The grey edge is something to do with it carrying on cooking after you actually take it out of the water. Get it cold quickly, and you'll avoid the grey.

Its the sulphur in the egg (that which gives rotten eggs their distinctive hydrogen sulphide rotten eggs smell) forming compounds if its overcooked. Overcook it enough and they will form throughout the yolk which will turn black. The extreme is the Chinese "thousand year old" eggs that are totally black including the whites.

My uncle used to sell fertilised hens' eggs to incubators to hatch out. I used to be freaked out for a while after staying on his farm when I was small during the summer holidays, worrying that every boiled egg I cracked open would have a chick in it... still uneasy even now.

Go to the Philippines and try Balut (sp) they are Duck eggs and the young chicks inside are very developed (some with feathers) but the locals eat them more as a savoury snack. I've tried them but am not impressed!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Thank you for the input

I plunged them into a bowl of cold water, as soon as they came out of the saucepan. Perhaps I will try running them under a cold tap next time.

FYI - I chucked them in the bin last night before posting this but wanted to know, for future reference! I will have another crack at it this evening

I don't think there's anything unsafe about eating them with grey yolk edges* - it's just a bit unsightly.

*at least, I've never come to any harm, and lots of my hard boiled eggs are like that because I often can't be bothered with the running under the cold tap bit.

Yep - I lived dangerously on Monday and ate 2, that were in this state. No obvious after effects!
I just wanted to be sure though and didn't fancy 'em last night!

They're fine to eat. Undercooked can be a problem though but nothing like the problem of undercooked kidney beans.
