A juicy and flavorful prime rib roast seasoned with a rosemary and fennel pollen rub, roasted to perfection, and served with a creamy horseradish sauce made from the meat juices, sour cream, horseradish, lemon, salt, and pepper.
Letting the prime rib rest before cooking ensures even cooking, and resting after roasting allows juices to redistribute for maximum juiciness. The fennel pollen adds a unique sweet and pungent flavor to the rub, enhancing the overall taste.
