Doh, why didn't I think of that coffee filter papers will definitely collect the fat globules.
I might be being daft but how will the arrowroot help to clarify, I agree it thickens without making sauces cloudy but I'm not sure where you are going there Barmaid???
I have no idea!!! I was just thinking of some "out there" ideas. Whenever I use it, it always seems to make things clearer - although I accept it wont take out the lumps (not that I am suggesting you make lumpy stock).
I'll shut up now ;) on the basis that when you've hit rock, stop friggin diggin.
The fat globules will also block the filter so you need to put the least fatty and the clearest liquid through first. I sometimes use a few layers of kitchen towel as a pre-filter to delay the clogging of the filters. ( not that I have used them for this process, more for alcoholic stuff)
Jomifl I've left it over night to go cold and have remove the hardened fat already so it isn't too fatty. I will pass through muslin (if I can find some clean stuff) or a j cloth and will go for a final pass through filter papers.
It won't be as good as using egg white or the freeze filtration method but it will suffice and if not I'll abandon the consome idea.
