Why it works: Butter and flour 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 ↓
Roast Wild Duck
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.
Prepare and roast
Truss the wild duck.
To reduce any fishy taste, baste the duck with hot water mixed with an onion and a little coarse sea salt before switching to butter.
Roast the duck in a 400°F (200°C) oven for 20 to 35 minutes, depending on your preference.
Do not baste the duck for the first 5 minutes to keep the gravy in.
Baste the duck generously with butter after the first 5 minutes.
Finish and serve
Baste the duck again a few minutes before serving.
Lightly dredge the duck with flour a few minutes before serving.
Serve the duck with a good gravy or orange gravy.
Garnish the duck with a cut lemon.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Wild duck
- Is the main protein; its rich, gamy flesh is the centrepiece of the dish.
- Butter
- Adds fat and moisture to the skin during basting, promoting browning and a rich flavour.
- Flour
- Lightly dusted on the duck before serving, it helps the surface brown and thickens the gravy.
- Onion
- Simmered in the hot water basting liquid, it adds aroma that helps mask a fishy taste.
The step that matters
Delaying the first basting. Basting in the first 5 minutes is skipped so the fat and juices stay in the pan for the gravy and the skin is not chilled by liquid. Wait until the skin has begun to render and firm before basting with butter.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour):
- Shallotfits better
- Leekfits better
- Arrowrootfits better
- Onionthe original
Fit is the average pairing score against butter, flour. Candidates are from the same food group and used in at least 100 recipes.
