When a recipe calls for the separation of the whites and the yolks, it is usually to make the best of the qualities of each of the egg's components. When you beat the yolks with sugar, etc., you can make a rich, creamy mixture that adds a distinctive quality to baked goods and sauces.
Whipping the whites incorporates a great deal of air and lightness to the batter. This allows the cake to rise better and other desserts to have a lighter feel. When the eggs are kept whole, the cake may still rise, but it will lose that airy quality that you can only get when you whip the whites on their own and then incorporate it into the batter with the yolks.
Of course, those who have difficulty with cholesterol will find a need to separate the whites from the yolks for a different reason. They may eliminate the yolks from the recipe altogether in order to retain the light quality that eggs give a recipe, but without the cholesterol the yolks contain.
How do you usually separate eggs? My only experience previously of separating eggs went like this: I cracked an egg, holding the yolk carefully in half the shell, letting the white drip into the bowl and keeping the yolk in the half shell. Then comes the part when I'd transfer the yolk back and forth between the two halves until all the white was in the bowl. At this point, I'd drop the yolks into a second bowl and toss the shells into the compost.
Easy enough, but the process was often less than effective, as bits of yolk sometimes dripped into the whites. Although not a catastrophe, this accidental mixture can interfere with the whites' ability to be whipped up properly.
I hadn't thought all of this was such a big deal until I found the video that has changed how I approach separating my eggs now.

Ha . I love the plastic bottle method .
Great post.
OMG I love this info, I hate separating eggs. Thank you so much for sharing this information!
Thanks for your comment, Thamisgith. And thanks for the heads-up on the first video. You used to be able to watch it embedded, so they must have changed their rules. I'm going to delete it here, but if anyone wants to see how eggs are separated by the food industry, you can watch the video on Youtube: http://youtu.be/0MszLow2uEI
Good info. My wife just has a "white" omelette, so quite topical for me.
Your first video is barred from embedding btw. The second one is more relevant for me anyway. I doubt if I'll ever need to separate hundreds of yolks, unless my better half is really hungry, but the trick with the water bottle is way cool.
Sometimes simple is the best.
I was using halves of eggs for many years and had the same problem. After I got a separator this process became really easy. Never hear for the trick with the bottle before. It is simple idea and it works like a bomb!
Mira, it is amazing, isn't it? And yet I feel it makes so much sense.
What a fun way to separate yolks, indeed! :) I kept watching that bottle and marveling at it. Thank you for sharing!
I hope they enjoy it!
That's great 2uesday! I like the bottle method because it's kind of funny, but the Yolky gadget takes up less room.
