What parts did you use?? I find that I wings make excellent soup. I add a few thighs since wings have no meat on them to pick off later. I also have never heard of putting the bones back in later like you mentioned. Perhaps that had something to do with the greasiness? I never tried making matzoh balls, so I have no suggestions there for you.

It sounds pretty darned good, though. Maybe you should ship a few off to JG, since he seems to need some Jewish penicillin right about now.
