I made Boeuf Bourguignon this weekend with short ribs. I cut the meat off the bone as well as the layer of fat when I had to. I now have 3-4 pounds of bones and trimmings. My idea is to roast the bones and trimmings at 450-500F for around 30-45 minutes and then throw them in a pressure cooker with carrots, an onion, leeks, and water for 45-60 minutes at high pressure. That should give me a decent stock? I was also thinking of making a jus instead with them - deglazing the pan every 5-10 minutes with water to build up a concentrated jus, bur I’m not sure how that would go with the fatty trimmings.
Any other ideas? Thanks!
