Ingredients
Ducks
2 (5½- to 6-pound) whole Pekin ducks, neck and giblets discarded¼ cup plus 2 teaspoons kosher salt, divided2 navel oranges, halved4 cups water ½ cup soy sauce ¼ cup honeyBlackberry Sauce
15 ounces (3 cups) fresh or frozen blackberries ¾ cup honey ¾ cup plus ½ teaspoon sherry vinegar, divided3 sprigs fresh thyme ¼ teaspoon pepperBefore You Begin
Pekin ducks may also be labeled as Long Island ducks and are typically sold frozen. Thaw the ducks in the refrigerator for 24 to 48 hours. This recipe was developed with Diamond Crystal kosher salt; if using Morton kosher salt, rub 1½ teaspoons into cavity of each duck and 1¼ tablespoons onto skins in step 2. We prefer to salt the ducks for 48 hours before roasting them for deeper seasoning and crispier skin, but they will still be very good after 24 hours. Avoid buying presalted ducks for this recipe. Even when the ducks are fully cooked, their juices will have a reddish hue.
Instructions
- Set wire rack in rimmed baking sheet. Working with 1 duck at a time, use your hands to remove large fat deposits from cavity opening of 2 whole Pekin ducks. Using kitchen shears, trim excess neck skin from top of breast and from cavity; remove tail and first 2 segments from each wing, leaving only drumette.
- Rub 2 teaspoons kosher salt into cavity of each duck. Rub remaining 10 teaspoons salt onto skins of ducks (5 teaspoons on each duck). Place ducks on prepared rack. Refrigerate uncovered for 24 to 48 hours.
- Adjust oven rack to lower-middle position and heat oven to 300 degrees. Set V-rack in roasting pan. Stuff cavity of each duck with 2 navel orange halves. Tie legs together with kitchen twine. Position ducks breast side up crosswise in V-rack, in opposite directions, leaving space between ducks.
- Bring 4 cups water, ½ cup soy sauce, and ¼ cup honey to boil in small saucepan over high heat; remove from heat. Ladle boiling water mixture over tops of ducks, allowing mixture to pool in bottom of roasting pan. Roast ducks until thermometer inserted into thickest parts of thighs registers 190 to 195 degrees, 3¼ to 3½ hours.
- Remove ducks from oven and increase temperature to 450 degrees. Once oven has reached 450 degrees, continue to roast ducks until skin is deeply browned all over, 10 to 25 minutes.
- Let ducks rest on V-rack in pan for 45 minutes.
- Bring 3 cups blackberries, ¾ cup honey, ¾ cup sherry vinegar, 3 sprigs thyme, and ¼ teaspoon pepper to boil in medium saucepan over medium-high heat. Cook, stirring often and mashing berries with potato masher, until mixture is thickened and registers 218 to 220 degrees, 15 to 20 minutes.
- Strain mixture through fine-mesh strainer into bowl, scraping strainer and pressing on solids to extract as much sauce as possible; discard solids.
- Stir remaining ½ teaspoon vinegar into sauce. Season with salt to taste and transfer to serving bowl. Let sauce cool slightly before serving; it will thicken as it cools.
- Carve ducks and serve, passing sauce separately.

Why This Recipe Works
While many recipes for roast duck call for scoring or pricking the skin and often for turning the bird multiple times, we were looking for a simpler approach. Salting the ducks well in advance—48 hours was best—seasoned them thoroughly; helped to keep them juicy during long cooking; and produced the driest, crispiest skin. Ladling a hot mixture of water, soy sauce, and honey over the ducks’ skin before roasting yielded birds with a lacquered shine while adding complex umami and depth. Roasting the ducks low and slow (300 degrees for over 3 hours) produced supertender, succulent meat, and blasting them briefly at 450 degrees finished rendering the fat and crisped the skin. We also made a simple sweet and sour blackberry sauce by cooking down whole berries with honey, sherry vinegar, and thyme. It is a perfect complement to roast duck, pork, or game.
