Pressure Cooker Beef Bone Broth
Put beef bones in roasting pan. Coat with tomato paste. (next time ifI don't have tomato paste I may try a little brown sugar and or oil? I think the point is to help the beef bones carmelize)
Bake/roast in 400 F oven for an hour. It will smell delicious.
Transfer roasted bones to pressure cooker. Pour hot water into the roasting pan and scrape up the bits, pour into the pressure cooker. Add more water to cover. Usually want to fill 1/2 to 2/3 of the pressure cooker with liquid for broth- follow the manufacturer's instructions (i.e. don't overfill)
Bring up to pressure. Cook over pressure for 25 minutes.
Strain. Pour into containers. I like to refrigerate first, which makes it easier to scrape off the fat. Then you can freeze for later use.
