Why it works: Pepper and butter are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 85,593 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Long Island Roast Duckling
3–4Ingredients
Directions
Prepare the duckling
Preheat oven to 450°F.
Rinse and wipe the duckling, removing giblets.
Set the bird aside in an airy place to allow the skin to dry.
Rub the inside cavity with salt and pepper.
Insert the vertical oven roaster into the bird and prop it upright.
Coat the bird on all sides with butter-flavored spray and sprinkle salt and pepper lightly over the skin.
Roast and serve
Place the bird and vertical roaster into a large roasting pan (use a wire rack insert if you have one) and add ½ cup water to the bottom of the pan.
Leave the bird in the oven for 30 minutes.
Reduce the oven temperature to 325°F and continue cooking until done.
Do not prick the skin or baste the bird; the fat will render off, leaving a crispy skin.
Keep the bottom of the roasting pan covered with water to prevent smoking.
Pour off the fat and save it, reserving the drippings and liquid from the roasting pan.

What each ingredient does
- Duckling
- Provides the meat and fat that render during roasting to crisp the skin.
- Salt
- Seasons the skin and cavity and helps draw out moisture for a drier surface.
- Butter-flavored spray
- Adds a thin fat coating that promotes browning and carries a buttery aroma.
The step that matters
Do not prick the skin or baste the bird. Duck skin is rich in fat that needs to render slowly out of the skin. Piercing the skin or basting lets fat escape unevenly and can add moisture to the surface, which slows crisping and leaves the skin less crisp.
