1 Standing rib roast, approximately 8 Lb.
3 Jars pure grated horseradish (white)
Garlic cloves (about 6)
Cut the garlic cloves into spears. Spear the roast, shoving the clove spears deep inside with a finger. Lightly salt and pepper the roast. Encase the roast in horseradish, on all sides. Place tin foil on the grill rack. Cook on a low-flame gas grill for about 3.5 hours, turning as necessary. Let sit for about 10 minutes to set. Carve and serve.
