Prime rib does not need a lot of fancy marinades or rubs IMO. The meat speaks for itself. A simple rub of salt, black pepper, garlic powder, and maybe some thyme or oregano. I have added some dry mustard in the past as well. The recipe by aawa follows the same principle and looks good.
A friend is cooking a prime rib and needs a rub recipe. Who has a good one that is not overly complicated?
A bag of Oakridge BBQ's Black Ops. Best rub I've ever used on a rib roast. Premade and ready to use.
