Into a tray, add all your bones, feet, or tendon depending on which version you decide to make. (beef or chicken)
5 lbs beef neck bones, 3 lbs beef tendons, 4 lbs chicken carcass, 4 lbs chicken feet
Roast in an oven at 425F for 20 minutes or until charred.
Place all your bones into a pressure cooker and then add just enough water to cover the bones. You may also add vegetables to this, however, I like to give bone broth to my dog so I keep it as simple as possible.
water
Pressure cook on high for 1 hour, allow it to naturally release pressure.
Remove the bones into a separate bowl and using a fine mesh sieve, strain the broth out into a heat safe bowl.
Cover and place our broth in the fridge overnight. The fat will rise to the top and solidify.
Remove the fat, and you will be left with extremely gelatinous broth.
To drink, I microwave for 2 minutes.
