1In a large container, submerge the prime rib in 1 gallon of whole milk.
2Add the entire bottle of Creole butter to the milk and mix well.
3Using an injector, inject the milk and Creole butter mixture into the prime rib on all sides.
4Cover and refrigerate for 24 hours.
5After 24 hours, remove the prime rib from the refrigerator and dry it thoroughly with paper towels.
6Carefully cut towards the bone on the backside to trim off excess fat, including the fat cap.
7Tie the prime rib with 4 pieces of long twine to hold it together while it rests.
8Let the prime rib rest for 1-2 hours until it gets to room temperature.
9In a bowl, mix together the mayonnaise, stone-ground mustard, and Dan-O’s Preem-O until well combined.
10Rub the seasoning concoction all over the prime rib, making sure to cover all sides and the bottom. Sprinkle additional Dan-O’s Preem-O generously on top.
11Preheat the oven to 275°F (135°C).
12Place the seasoned prime rib in the center of a baking pan with a rack.
13Bake the prime rib at 275°F for 2 hours.
14After 2 hours, increase the oven temperature to 300°F (150°C) and cook for an additional 50 minutes.
15Finally, crank the oven up to 500°F (260°C) and roast for 10 minutes to achieve a nice crust.
16Once cooked, remove the prime rib from the oven and let it rest for 2 hours, covered with foil.
17After resting, cut off the twine and skewer.
