Dry aged rib roast is the height of luxury: and the secret is, it's so easy to do at home.
– Prime rib roast – Soy sauce – Salt – Pepper
Prepare a roasting pan with a rack, and place the rib roast on the rack. Pat it dry all over with paper towel.
Use a basting brush to brush the roast all over with soy sauce, on all sides of the meat.
Coat all sides of the meat very generously with salt and pepper.
Place the roasting rack and prime rib in the fridge, uncovered, and let it rest for 10-20 days.
Once done, you'll see that the surface of the meat is dry in appearance. Remove from the fridge, let rest 30 minutes, then cook as desired!
