I was explaining to my friend, Sharon, about the old 'if the egg floats' rule, but now I can't remember for sure which is which. If the egg floats it is bad --- or if the egg sinks????? I really do think that the floaters are bad --- sulfur dioxide gas? But.....? I've got one of each in the fridge right now, but I am not eating them both to see which one makes me sick.
