A weird concept....how? Doesn't your meat, chicken, cheese and all
other fresh grocery items have "sell by" "use by" or "expiration"
dates? Where do you live? Eggs that are past their prime are just as
nasty as any other spoiled or not fresh product. This morning I
cracked an egg and it flowed from the shell like water...the white was
thin and clear, and the yolk broke immediately. I threw it out. And
they were from a "NEW" dozen, too. A fresh egg has a cloudy white,
and definite demarkation where the yolk sits up high on the whites.
"Older" eggs are better for boiling. But I wouldn't go too far over
the date. A few days, maybe.
