I had this problem and managed to find an egg separator in a local kitchen shop (apparently it was made somewhere in Scandinavia and they're rare in the UK but don't know about other countries). It's like a little china jug with a slit halfway up one side. You break the egg in and tilt it so that the white pours through the slit into your mixing bowl and the yolk stays put. Perfect for me as I'm a bit of a klutz - and can't imagine lc life without Cleo's oopsie rolls!
