I believe I've read that yolks freeze pretty well so if you get an egg separator , you'll be in good shape. (Never know when you'll get an urge to make a super-rich cake or custard that calls for different amounts of yolks and whites.)
These lovely devices come in a variety of styles, most often I've seen ones that look like a measuring cup with slots cut in the sides near the bottom so that the yolk is resting while the white oozes out.
One of the least tasteful ones I've seen (while googling this just now) is this lovely ceramic one. I'm not sure I'd still have an appetite for whatever it was I was intending the whites for in the first place after using this guy.
The problem with that is, I have them 5 days a week - early in the morning before going off to work - cracking shells and seperating them is a length process hence in USA/UK we can buy pure egg whites
In short - no, we don't have them. The egg white low carb thing has not caught on here, people on a similar track tend to opt for protein shakes instead.
Lazy? I'm in the gym 6 days a week mate - I wake up for early morning jogs - I'm a semi professional boxer - I have a routine and people like me, the egg whites thing is really handy
Well, I can only say either do it the night before, as someone suggested, or get up 5 mintues earlier to separate them. Only takes a few seconds per egg.
Ok, if you eat that many eggs and want things handy, there is perhaps another solution for you.
Around here, there is an egg farmers cooperative, www.labeye.ch , that delivers fresh eggs to your house, very good quality and price delivered at home. Perhaps there is something similar in your area. If a professional boxer and succesful, and want things handy, I suggest you use that income to pay the farmer's daughter to crack the eggs for you each morning upon delivery.
ps--it could be that Labeye even delivers to your area.
I'm on a slow carb diet at the moment to shift a few pounds and watched Tim Ferriss make a slow carb breakfast of egg whites, spinach, lemon juice and salsa. He managed to avoid using any product in its original form. Everything was out of a packet and then nuked in the microwave
Purely out of curiosity I had a look locally when out shopping to see if I could find egg whites in a jar and was rather relieved to find I couldn't! I'd suggest separating your eggs manually and doing a few days at a time. This way you could store it in a sealed container to be used in the morning.
