Perfect Prime Rib - cooking recipe

Ingredients

7 lbs first-cut beef rib roast, 3 ribs
1 tablespoon vegetable oil

Preparation

Let roast set at room temperature 3 hours.
Using kitchen twine parallel to the bone, tie roast at both ends to keep outer layer from pulling away and overcooking.
Adjust oven rack to lowest position and preheat to 200. (yes, 200).
Pat roast dry with paper towels.
Heat oil in large pan over 2 burners set at medium-high. Place roast in pan and cook on all sides until nicely browned and about 1/2 cup of fat has been rendered, 6-8 minutes.
Remove roast from pan. Spoon off fat from pan. Set wire rack in pan, then set roast on rack. Season with salt and pepper.
Place roast in oven and roast until meat registers 125 (medium-rare) about 3 1/2 hours (30 minutes per pound),
Let rest about 20 minutes.
Transfer to carving board and carve; serve.
