Preparation

• In a small bowl, combine 1 Tbs. each of the oil and sambuca with the garlic, rosemary, fennel seeds, coriander, 1-1/2 Tbs. salt, and 3/4 tsp. pepper to make a paste; set aside.
• Pat the roast dry with paper towels. Rub the paste over the entire roast. Cover and refrigerate overnight.
• Position a rack in the center of the oven and heat the oven to 400°F.
• Arrange the potatoes, parsnips, onions, and fennel in a 13×17-inch (or similar) roasting pan, season with 1/2 tsp. salt and 1/8 tsp. pepper, and drizzle with the remaining 1/4 cup olive oil. Roast, turning occasionally, until a fork inserted in the center of each type of vegetable meets little resistance, about 40 minutes.
• Meanwhile, remove the roast from the refrigerator and let sit at room temperature for 30 minutes.
• Reduce the oven temperature to 300°F. Put the roast, fat side up, on top of the vegetables. Add the chicken broth and wine, and roast, basting the meat and vegetables occasionally, until an instant-read thermometer inserted into the roast registers 135°F to 140°F, about 2 hours.
• Transfer the roast to a serving platter or carving board, cover loosely with foil, and let rest for 20 to 30 minutes. With a slotted spoon, transfer the vegetables to a large sheet of foil; wrap and keep warm in the turned-off oven.
• Pour the juice from the roasting pan into a fat separator and let sit until the fat rises to the top. Pour the clear juice into a 1-quart saucepan, leaving the fat behind, and put over medium-high heat. Add the remaining 1 Tbs. sambuca and simmer until the jus is slightly reduced, 3 to 5 minutes. Strain through a fine sieve and season to taste with salt and pepper.
• Arrange the pork on a platter with the vegetables, garnish with the fennel fronds, and serve with the jus on the side.

Orange-Soaked Bundt Cake makes a wonderful dessert.
