I liked this broth; I used it to make an excellent soup (mushroom and thyme, my own recipe), and it also made a good broth on its own. I am noting the details here for my own reference and for anyone else that's interested. I used 2 packs of beef bones and 5 chicken backs. Roasted at 450 for 30 minutes. Placed in 6 Q instant pot with 3 quarts water and the remaining ingredients as listed (I would reduce salt next time a bit). Cooked on high setting 2.5 hours natural release. Total time including roasting was about 4 hours 15 minutes. More time needed to cool broth if necessary. Once cooled and refrigerated it gelled up nicely.
