Place the prime rib in a large, non-reactive container. Pour 1 gallon of whole milk over the prime rib, ensuring it is fully submerged. Add the Creole butter sauce to the milk.

Using a meat injector, inject additional whole milk directly into various points of the prime rib for approximately 5 minutes, ensuring deep penetration of the marinade.

Cover the container and refrigerate the prime rib to marinate in the milk mixture for a full 24 hours.

After 24 hours, remove the prime rib from the refrigerator and discard the marinade. Allow the prime rib to come to room temperature for at least 1 hour. Thoroughly pat the prime rib dry with paper towels.

Carefully cut and remove the bones from the prime rib. Trim any large fat caps from the meat.

Using butcher's twine, tie the prime rib at 1-inch intervals to help it maintain its shape and ensure even cooking. A good guide is to wrap the twine around your arm four times for the length needed for each tie.

Let the tied prime rib rest at room temperature for another 2 hours.

Preheat your oven to 450°F. In a medium bowl, combine the mayonnaise, stone ground mustard, and 1/4 cup of Dan-O's Primo Seasoning. Mix thoroughly until a smooth paste forms.

Spread the prepared seasoning paste generously over all surfaces of the prime rib, ensuring a thick, even coating. Sprinkle additional Dan-O's Primo Seasoning over the top for extra flavor and crust development.

Place the seasoned prime rib on a wire rack set over a baking pan. Transfer to the preheated oven and roast for 15 minutes.

Reduce the oven temperature to 325°F and continue to roast until the internal temperature reaches your desired doneness (e.g., 125-130°F for rare, 130-135°F for medium-rare). This will take approximately 2 to 2 1/2 hours.

Once the prime rib reaches the desired internal temperature, remove it from the oven. Tent loosely with aluminum foil and let it rest for at least 20-30 minutes before carving. This allows the juices to redistribute, ensuring a tender and flavorful roast.
