Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

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.
Roast
Preheat your oven to 400°F (200°C).
Choose two fat ducklings and roast them for about 30 minutes.
Finish and serve
Just before removing them from the oven, sprinkle a little flour and coarse sea salt over the ducklings.
Baste the ducklings with butter.
Ensure the gravy is rich and good, but not black.
Serve immediately after roasting.

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.

Shared aroma: isobutyraldehyde (malty, green).
Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

What each ingredient does
- Fat ducklings
- Provide the meat, and their rendering fat flavours the dish and keeps it moist.
- Flour
- Browns in the pan drippings and thickens the gravy.
- Butter
- Adds fat for basting, which promotes browning and a richer flavour.
The step that matters
Sprinkling the flour just before removing the ducklings. Flour browns quickly at high oven heat. Adding it late forms a light crust and thickens the drippings, while adding it early risks scorching the gravy black and bitter.
