re: just struck out on first Prime Rib. What happened?

---

cooked for 32 mins at 500 and let sit in the oven for 2 hours without opening.

for two hours you were not at appropriate temps

Cook at 500 if you want, but lower the temp after about 20 minutes, then set at 325 or so and go for the rest. You are looking in the neighborhood of 12-15 minutes per pound.

If you invest in a rib roast, invest in a meat thermometer.

Let rest a long time prior to carving, you will still get enough drippings for a board sauce (thank you F&DB for that tip)
