1. Heat oven to 425 degrees. Position rack in lower third of the oven.

2. Prepare the crown roast of pork as you would any other roast; begin by seasoning with salt and pepper, and brush meat with 4 tablespoons olive oil.

3. In small bowl, combine orange zest, garlic, rosemary, and the remaining 1 1/2 tablespoons olive oil. Spread mixture evenly over the meat, inside and out. Place meat in a heavy-duty roasting pan with a rack large enough to hold roast without crowding sides. Roast 15 minutes. Reduce heat to 375 degrees. Continue roasting, rotating pan after 45 minutes, until meat is well browned and an instant-read thermometer registers 150 degrees, about 1 1/2 hours. (Insert thermometer into meaty center of the crown, making sure that it does not touch any ribs. Take several readings to ensure that temperature is even all around.)

4. While the crown roast is cooking, make the Wild-Rice Dressing. Remove roast from oven, transfer to a cutting board with a well, and let stand 20 minutes. Raise oven temperature to 425 degrees. Place dressing in oven, and bake until heated through, about 20 minutes. Pour the pan juices into a fat separator or glass measuring cup, and let stand 5 to 10 minutes. If using a separator, carefully pour juice back into pan; discard fat. If using a measuring cup, carefully remove fat with a spoon, and return juices to pan. Place roasting pan on top of stove over medium-high heat. Add the wine, and bring to a boil. Using a wooden spoon, stir up any brown bits on the bottom of the pan. Boil until half of the liquid has evaporated, 5 to 7 minutes. Stir in apple cider and stock; season with salt and pepper, and return liquid to a boil. In a small bowl, combine the butter with the flour. Mix until completely combined. Transfer this mixture to the roasting pan. Whisk constantly until the gravy has slightly thickened, 4 to 5 minutes. Remove pan from heat, and strain liquid into a gravy boat.

5. Carefully lift roast out of pan, and place on a serving platter; spoon the dressing into the center of the roast, and carve.
