Someone’s never come home with a slightly cracked egg that’s glued itself and three friends to the carton.

If you’re that pressed for time, turn the carton over. You’ll see a darker color if one has cracked and it’ll feel off when one or more doesn’t move.

Okay, so the truth of this is, yeah people check for cracked eggs, but there’s more to it…

It’s extremely important to make sure all the eggs have the proper luminosity. You can tell this by opening the carton and holding the eggs up against the lighting. Eggs with the correct luminosity will reflect a cooler tone - no less than 5,500K, while eggs that are of poor quality will reflect a more yellowish or reddish hue. Eggs with the correct luminosity contain higher amounts of vitamin D and B12, and are generally better for use as binding agents in various recipes.
