Festive Roast Duck with Duck-Pork Sausage Rolls and Spiced Cherry Sauce

Pat the whole duck thoroughly dry inside and out using paper towels on a sanitized cutting board, ensuring hands and work surfaces are washed promptly to avoid cross-contamination.

Score the duck breast skin in a tight diamond pattern using a sharp chef's knife, scoring only through the fat layer without slicing into the flesh.

Season the cavity and entire exterior of the duck evenly with kosher salt, Chinese five-spice powder, and cracked black pepper, then stuff the cavity with the halved orange, halved garlic head, and fresh thyme sprigs.

Preheat the oven to 160C (320F) with the oven rack positioned in the lower third.

Roast the seasoned duck breast-side up on a wire rack set inside a roasting pan at 160C (320F) for 1 hour and 45 minutes to render out subcutaneous fat.

Drain the accumulated rendered fat from the bottom of the roasting pan through a fine-mesh sieve into a heatproof container, setting it aside for other uses.

Roast the duck at an increased temperature of 220C (428F) for 20 minutes until the skin turns deeply bronzed and crisp and a digital instant-read meat thermometer inserted into the thickest part of the thigh away from bone registers at least 74C (165F).

Rest the whole roast duck on the wire rack at room temperature for 20 minutes before carving to allow juices to redistribute throughout the muscle fibers.

Mix ground pork, ground duck, minced shallot, minced garlic, chopped sage, fine sea salt, ground nutmeg, and panko breadcrumbs together in a large mixing bowl until evenly blended into a cohesive farce.

Roll out the chilled all-butter puff pastry sheet on a sheet of parchment paper into a rectangle measuring roughly 25cm by 35cm.

Shape the meat mixture into a long, uniform cylinder running down the center of the pastry sheet, then fold the pastry tightly over the filling to encase it, pressing the seam firmly to seal.

Glaze the entire pastry log surface evenly with the beaten egg using a pastry brush, then sprinkle nigella seeds over the top.

Slice the pastry log seam-side down with a sharp chef's knife into 6 equal sausage rolls, transferring them spaced 5cm apart onto a rimmed baking sheet lined with parchment paper.

Bake the sausage rolls at 200C (392F) for 25 minutes until puffed, deeply golden, and a digital instant-read meat thermometer inserted into the center of the meat filling registers at least 71C (160F).

Simmer sweet dark cherries, duck stock, ruby port, red wine vinegar, dark brown sugar, whole star anise, and the cinnamon stick together in a medium saucepan over medium heat.

Reduce the cherry sauce over medium-low heat for 10 minutes until the liquid reduces by roughly one-third and cherries soften slightly, then pluck out and discard the star anise and cinnamon stick.

Whisk cornstarch and cold water together in a small mixing bowl to create a smooth slurry, pour into the simmering sauce, and whisk continuously for 1 minute until clear and lightly glossy.

Emulsify cold cubed butter into the warm sauce off the heat by swirling the pan and whisking gently until fully incorporated and velvety.

Slice the rested roast duck into breasts cut on a bias and separate the legs and thighs using a sharp chef's knife on a cutting board.

Plate portions of warm roast duck accompanied by a golden duck-pork sausage roll and spoon the spiced cherry sauce generously alongside the meat.
