Tonight I tried this method of separating eggs. I tried it on 3 sizes of eggs and found that on a grade AA large egg it works perfectly. On an extra large egg, while the bottle will suck up the yolk, it may also break it. Even broken, the yolk stays in the bottle.
Finally I tried this on some medium eggs and it also worked well, in fact, I was able to suck up several yolks without emptying the bottle so I ended up with a bowl full of whites and a bottle full of yolks. I then shook the bottle to "beat" the eggs and poured the yolks in a thin stream into my pot of cooking soup (a la eggdrop soup). Cool experiment - btw - the egg completely wrecked my sunchoke soup ;)
Forget love... I'd rather fall in chocolate!
