I use a similar recipe posted from the westonaprice.org website. My family thinks I'm nuts for saving feet for broth, though. One idea is to save carrot tops, celery hearts, onion tops and bottoms, and other assorted veggie parts that might go to waste in a gallon bag in the freezer to throw into the stock. I also like to toss in some dandelion leaves towards the end for their high mineral content along with the parsley. I always strain alone so my husband doesn't see the chicken and turkey feet!
