Duck Rillettes

Step 1
Preheat the oven to 250 degrees F (120 degrees C). Line a 9×13-baking dish with two pieces of aluminum foil.

Step 2
Make the spice rub: Stir kosher salt, pepper, and thyme together in a small bowl. Make the seasoning mix: Mix garlic, thyme sprigs, garlic, ginger, and bay leaves together in another bowl.

Step 3
Season duck all over, both inside and out, with about 2/3 of the spice rub. Fill the cavity with all of the seasoning mix. Place duck, breast-side up, into the prepared baking dish and season with remaining spice rub. Wrap duck tightly in aluminum foil.

Step 4
Roast in the preheated oven until meat pulls away from the bones, 5 to 6 hours. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C). Cool duck with its accumulated juices, wrapped in aluminum foil, to room temperature, about 1 hour. Chill in the refrigerator for 12 hours.

Step 5
Pick meat from the bones and place into a bowl.

Step 6
Spoon all accumulated juices in the foil into a saucepan and set over medium-high heat. Cook until hot throughout, about 5 minutes. Strain juices through a fine-mesh strainer into a bowl. Let fat and stock separate, then transfer fat from the top to another bowl.

Step 7
Mash duck meat, 3 tablespoons duck fat, 2 tablespoons duck stock, butter, brandy, parsley, chives, Dijon mustard, cayenne pepper, salt, and black pepper together in a bowl with a wooden spoon. Transfer to to a sealable container, press down, and drizzle a little duck fat over the top. Sprinkle thyme leaves, more black pepper, and orange zest over the top. Seal the container and refrigerate for the flavors to blend, 1 to 3 days.
