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 ↓
Roast Duck-partridges
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 400°F (200°C).
Season the duckling inside and out with coarse sea salt and pepper.
Place the duckling in a roasting pan and rub the skin with butter.
Roast and rest
Roast in the preheated oven for about 1 hour, or until the skin is golden and crispy.
Let the duck rest for 10 minutes before carving.

What each ingredient does
- Duckling
- Provides the main protein and fat that renders out as the bird roasts.
- Butter
- Adds fat to the skin, helping it brown and turn golden in the oven.
The step that matters
Roast until the skin is golden and crispy. Duck skin is thick and fatty, so it needs enough time at high heat for the fat to render out. Stopping early leaves the skin flabby and greasy, while the meat underneath still needs to cook through.
