1Decide whether to get prime rib on or off the bone. If on the bone, consider using bones for sauce or roasting them as ribs.
2Trim the fatty end of the prime rib, saving the fat for Yorkshire pudding or roast potatoes.
3Score the top of the beef in small squares, not going too deep.
4Douse the prime rib with Worcestershire sauce and rub it in all around.
5Prepare Rosemary salt by stripping rosemary and sage leaves, adding them to a food processor with peeled garlic, lemon zest, and salt, then blending for one minute.
6Generously season the prime rib all the way around with Rosemary salt.
