Number Of Ingredients 14

Ingredients

1/4 cup smooth Dijon mustard
1/4 cup grainy mustard
One 14- to 16-pound, 7-bone whole prime rib roast
1 tablespoon whole white peppercorns
1 tablespoon whole black peppercorns
1 tablespoon whole green peppercorns
1 tablespoon whole Sichuan peppercorns
Kosher salt
1 1/2 cups all-purpose flour
3/4 teaspoon kosher salt
3 eggs, preferably at room temperature
3/4 cup warm water
3/4 cup warm milk
1/2 cup unsalted butter, melted, plus a little extra for greasing the baking dish

Steps:

For the prime rib: In a medium bowl, combine the mustards and peppercorns. Stir to blend until it forms a paste. Place the prime rib in the roasting pan (fitted with a rack) you intend to cook it in. Place the roast, fat side up, and spread the peppercorn paste over the whole top. If marinating, refrigerate overnight.
For the Yorkshire pudding: In a medium bowl, combine the flour and salt. Stir to blend. Whisk in the eggs, one by one, and then the water. Refrigerate.
For the prime rib: Preheat the oven to 350 degrees F.
Remove the prime rib from the refrigerator about a half hour before cooking. This will allow the meat to come closer to room temperature and help the meat cook more evenly. Season the roast with salt. When the oven is hot, place the meat in the center of the oven. Allow it to cook 12 to 15 minutes per pound (2 1/2 to 3 hours). Cook until the meat reaches an internal temperature of 135 degrees F. When the roast is close to finished, remove the Yorkshire pudding mixture from the refrigerator to allow it to come close to room temperature. Then, remove the pan from the oven and allow the meat to rest at least 20 minutes before slicing.
To finish the Yorkshire pudding: Raise the temperature of the oven to 400 degrees F and place the baking dish for the Yorkshire pudding inside.
Whisk all of the warm milk and some of the melted butter into the batter. When the baking dish is hot, carefully remove it from the oven and quickly add the remaining melted butter to the dish. Pour the batter over the butter and place the dish in the center of the oven. Bake in the oven until golden brown and puffy, 30 minutes. Cut into 8 wedges and serve immediately with a slice of prime rib and some of the pan drippings.
