Grilled Pork Porterhouse With an Apple-Maple-Ginger Sauce

Preparation

1. For the Brine

   1. Step 1

      Twenty-four hours before cooking, stir all of the brine ingredients except the pork into 1 quart of water in a large pot and bring to a boil. Let cool to room temperature. Submerge the pork chops in the brine, cover and refrigerate.

   2. Step 2

      The next morning, prepare the infused oil: grind the coriander, bay leaf and peppercorns in a spice mill or a clean coffee grinder and combine with the remaining ingredients in a medium bowl. Let sit at room temperature.

   3. Step 3

      Make the sauce: In a saucepan, melt the butter over medium-low heat. Add the shallots and sauté until caramelized, about 4 minutes. Add the garlic and cook for 1 minute. Add the apple juice, chicken stock, star anise and ginger. Bring to a boil, lower the heat and simmer until reduced by one-quarter. Add the maple syrup, vanilla pod and seeds and agar and simmer for 3 minutes. Remove from the heat. Discard the star anise and vanilla pod. Purée the mixture in a blender or food processor, then pass through a fine-mesh sieve into a pan. Season to taste with salt and pepper.

   4. Step 4

      Prepare a charcoal or gas grill to medium-high heat. Rinse the meat and pat dry with paper towels. Brush the chops with the infused oil, then sprinkle lightly with salt. Grill to medium doneness, or until the internal temperature reads 135 to 140 degrees on a thermometer and the middle is light pink, about 6 minutes per side. Let sit for 5 minutes before serving. Drizzle with warm sauce and serve.
