World Egg Day: Everything You've Ever Wanted to Know About Eggs

“It may be the cock that crows, but it is the hen that lays the egg.” ~ Margaret Thatcher

Get your chalazae (the shock absorber that holds the yolk suspended in the shell) on, because Friday, October 12 marks World Egg Day, a day to celebrate these perfect oval bundles of high-quality protein. They can do it all -- bind, leaven, thicken, emulsify, clarify, scramble and poach. Here's some intel to make you a full-on eggs-pert.

Fresh Eggs

To tell if an egg is fresh, place it in cold, salted water. If it sinks, it’s super-fresh, if it stays suspended, it’s around two weeks old and if it floats to the top, toss it because it’s long past its expiry date.

Storing Eggs

Contrary to refrigerator advertisements, keep your eggs in the carton. Eggs have over 17,000 pores on the shells’ surface and can absorb unwanted flavours and odours. As well, be sure to store the carton on an inside shelf of the refrigerator as the door temperature is a few degrees warmer and can compromise the freshness of your eggs.

Brown Eggs v. White Eggs

There isn’t a difference in nutrition between white and brown eggs -- the shell colour comes from the type of hen that lays the egg.

Egg Mess

Dropped an egg on the floor? Sprinkle it heavily with salt, let it sit 10 minutes and it’ll be a breeze to clean up.

The Perfect Hard-Boiled Egg

In a saucepan, place eggs in a single layer and cover with cold water by 1 inch. Over medium-high heat, bring water to a rapid boil. Remove from heat, cover and let stand for 15 minutes. Drain and run eggs under icy water until cool.

Whipping Egg Whites

If you’re whipping egg whites into a frenzy, make sure you let them come to room temperature first -- you’ll get better results. If you're in a rush, place eggs in a bowl of warm water for 10 minutes to quickly bring them to room temperature.

Using Your Freezer

You can freeze your egg whites. Keep them in an airtight container and they’re good frozen for up to two weeks.
