- 1 (16 -18 lb) prime rib roast, tied at 2 inch intervals (7 ribs, 16-18 pounds)
- 6 garlic cloves, each clove cut lengthwise into 4 pieces
- 4 -6 sprigs fresh rosemary
- 2 tablespoons black peppercorns
- 2 tablespoons dried rosemary
- 2 tablespoons coarse salt
- 2 tablespoons sweet paprika
- Set up grill for indirect grilling and place a large drip pan in the center; preheat to medium.
- Using the tip of a slender paring knife, make a series of ½ inch deep holes in the roast, mostly in the sheath of fat on top, but also on the sides and bottom.
- The holes should be at least 2 inches apart.
- Insert slivers of garlic in half the holes; strip the leaves off 1 or 2 of the rosemary sprigs and insert them in the remaining holes.
- Slide the remaining rosemary sprigs under the string used to tie up the roast.
- Make the rub: grind the peppercorns and dried rosemary to a fine powder in a spice mill or blender.
- Add the salt and paprika and grind to mix; rub this mixture all over the roast, especially over the sheath of fat on top.
- When ready to cook, oil the grill grate; place the roast, fat side up, on the hot grate over the grill pan and cover the grill.
- Grill the roast until cooked to taste, 3 ½ to 4 hours for medium-rare for a roast this size (figure 12 to 14 minutes per pound); if using a gas grill, keep the cover closed at all times.
- Use an instant read thermometer to test doneness—you will want to cook the roast to 145° for medium-rare, 160° for medium.
- Transfer roast to a platter or carving board and cover loosely with foil.
- Let roast rest for 10-15 minutes before carving; easiest way to carve is to cut it into rib.
- sections with a long, slender knife, then into thin slices to serve.
