Paleo enthusiast Justin Mares was searching for a bone broth to help his brother Nick heal from an ACL tear in 2013. Online offerings were limited: non-organic, shipped with styrofoam, frozen. So he and Nick set out to develop their own recipe, and Kettle & Fire was born. They combine marrow bones with vegetables and filtered water in steel kettles. The mixture is slow-simmered for 24 hours, enough time for the marrow to release collagen and amino acids. The result: an organic, paleo broth in earth-friendly packaging.
