1. Preheat the oven to 325°F. 2. In a food processor, combine the butter with the garlic, horseradish, thyme, rosemary and sage and process to a paste. 3. Stand the roast in a very large roasting pan. 4. Season generously all over with salt and pepper and set it fatty side up. 5. Spread the horseradish-herb butter all over the top. 6. Bake for about 3 1/2 hours, until an instant-read thermometer inserted in the center registers 125°F for medium rare. 7. Transfer the roast to a carving board to rest for at least 20 minutes or for up to 1 hour before serving. ---------------------------------------------------------------------------
