Cook a chicken, either in the crockpot or the oven. Take most of the meat off the bones, saving the drippings and carcass. Throw it all in a pot and add some carrots, celery, bok choy, whatever veggies you have, for vitamins. I'm going to start adding Chicken feet and some raw drumsticks, but have to wait until next payday. You're probably not going to want to pick the veggies out, so don't fill the pot up. Add a splash of raw apple cider vinegar, fill pot with water. Simmer for 12-24 hours. Twenty-four hours is best.
Strain and fill jars or ziploc freezer bags with broth. If you have a pressure canner, you can preserve the broth by canning.
Use in recipes, as a tummy settler, or to make chicken soup (add chicken, veggies, and, if you desire - noodles)
