If you want truly amazing, collagen rich bone stock (the kind you need to make outstanding risotto, for example) you’ve got two choices: Make it at home by roasting bones and boiling them, a chicken, and a bunch of veggies in a giant pot for 8-10 hours, then filtering, refrigerating, and skimming the fat. Buy Kettle & Fire’s boxes. That’s it. So, do your friends a favor and buy them a carton of bone broth. Geraldine drinks the stuff for breakfast or lunch. I usually use it in recipes. Both are good applications.
