Yes, they can as well as egg whites. Whole eggs can be frozen if you beat slightly w/a few grains of salt or sugar. You can save in ice tray. 1 cube would equal 1 whole egg. I just read that in Susan G. Purdys book "The Perfect Cake"
After they are frozen, you just pop them out and put in a Ziplock. As long as they stay frozen they will last for a long time. You can also freeze them in recipe-sized blobs, just be sure to mark how many there are...been there, done that.
they can be frozen....i find that they dont "thaw" properly....i have made lemon curd with some and had to push it through a sieve because it was lumpy. but they can be frozen. the whites thaw perfectly.
