Just Good to know!
It seems that all the eggs on the market are guaranteed to be “farm fresh,” whether you’ve paid a dollar a dozen at a discount grocers or five times that much at a farmer’s market. How can you tell if an egg is truly fresh?
The quickest test is to crack an egg into a pan of slowly simmering water. The egg is fresh if the white is thick and clings to the yolk. The egg is old if the white is thin and spreads out into the water. A poached fresh egg presents a very tidy package.
Boiling an egg gives you more clues. Fresh eggs lay flat on the bottom of the pan. Older eggs tend to tilt upward. That’s because air has had time to infiltrate the shell and form an internal bubble. The bubble levitates one end of the egg. The older the egg, the steeper the incline.
Once your boiled eggs are done, peel one of them. The egg is very fresh if it’s difficult to peel and some of the cooked white pulls away with the shell. An older egg peels like a breeze. Fresh eggs make raggedy looking deviled eggs.
