This reverse sear method, which involves bringing the meat to temperature slowly in a low temp oven and then searing it quickly to lock in the flavor within a colorful crust, can help prevent overcooking the outside of the rib roast.
Helpful tip: having a probe thermometer is very helpful when roasting. Especially one you can leave in the roast and read the temperature easily, either from a display on the counter or remotely from your phone.
