I just found the coolest way to separate egg whites from the yolks (or vice versa). No need to buy a special egg separator. All you need is a very clean, empty water bottle and two small bowls. Watch this short video and see how cool this is. (Don't worry about the language barrier - you don't need to hear the words to understand the process.)
Was I right? Aren't you ready to grab an empty water bottle and an egg and try it out?
To give credit where credit is due, I found this video in my favorite recipe newsletter, Recipe du Jour. Unfortunately that newsletter is no longer published, but the archives are available at the link. Recommended!
Now grab a water bottle, separate those egg whites, and make yourself an omelet to celebrate!
