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 ↓
Butter-ball Duck
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat oven to 400°F (200°C).
Clean the duck and season it inside and out with salt and pepper.
Place the duck in a roasting pan and dot it with butter.
Roast and serve
Roast the duck in the oven for about 1 hour, or until the skin is crispy and the meat is cooked through.
Let it rest for a few minutes before carving and serving.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Wild duck
- The main protein; its fat renders as it roasts, crisping the skin and cooking the meat.
- Butter
- Adds fat that helps the skin brown and keeps the surface of the meat moist.
The step that matters
Roast until the skin is crispy and the meat is cooked through. Duck skin crisps only once its fat has rendered out over enough oven time, while the meat must reach full doneness. Because the roasting time is approximate, check doneness rather than relying on the clock alone.
