2. Trim excess fat from pork loin and trim extra meat from between rib bones. This is called “Frenching” the bones; you can also ask your butcher to do this). Rub all surfaces with crushed garlic and sprinkle generously with black pepper.
3. Place pork roast, bones up, on rack in shallow roasting pan. Roast for 1 to 1 1/2 hours (20 minutes per pound), until internal temperature on a thermometer reads 145 degrees F.
4. Remove roast from oven; let rest 10 minutes. Cut between rib bones to serve.
