This is a good idea, @donjonson. It won’t help right away, but the next time you roast something with bones, just pop the leftovers into a slow cooker, cover with cold water, and let the cooker do its thing for twenty-four hours or so. You can add more water periodically if it cooks out too fast. My sister likes to add a few veggies for flavor. When everything is nicely cooked, strain out the solids, and put the liquid in containers. Freeze what you can’t drink in a day or two. It’s actually dead easy, and takes altogether about ten minutes of actual work. Don’t add salt until the cooking is over, because whatever salt there is in the meat will be concentrated by the evaporation of the water, so you don’t want to end up with broth that’s too salty to drink.
