The broth is very, very good Marg. I left it in the slow cooker for 12 hours then it kept it warm another 8 (while I slept), I might even cook it longer next time as the flavour seemed to be much better in the morning than it was the night before. It didn't go gelatinous like some people seem to like but that's fine by me. I'm not feeling 'strong' enough to drink it straight but I made a delicious soup for lunch today with just some of the broth and random veg from the fridge.
I might have to invest in Nourishing Traditions, yes another book.
