Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Roast Wild Duck
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the duck
Do not dress the wild duck too soon after killing; keep it for several days in cold weather.
Preheat the oven to 400°F (200°C).
Roast
Bake the duck for 5 to 10 minutes without basting to retain the gravy.
Baste frequently with butter and water for 30 to 40 minutes until cooked.
Serve on a very hot dish with a cut lemon.
Make the sauce
For the sauce, combine Worcestershire sauce, mushroom catsup, salt, cayenne pepper, and lemon juice in a small saucepan.
Heat the sauce, remove from fire, and stir in prepared mustard.
Pour the sauce into a hot gravy boat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Wild duck
- Provides the meat that is roasted and served as the main dish.
- Worcestershire sauce
- Adds savory, tangy depth to the sauce.
- Mushroom catsup
- Adds concentrated savory umami flavor to the sauce.
- Lemon juice
- Adds acidity that brightens the rich, gamy duck flavor.
- Prepared mustard
- Adds sharpness and a mild emulsifying body to the sauce.
The step that matters
Bake without basting at first. Baking the duck uncovered and unbasted for the first few minutes lets the skin begin to render and set, while basting too early can wash away the surface and cool the oven heat, weakening browning and the gravy the record says to keep.
Swap the carrot
The recipe marks carrot as optional. How well each one fits the dish's main ingredients (sauce, mushroom, pepper, lemon, mustard, onion, butter):
- Shallotfits better
- Horseradishfits better
- Chivefits better
- Carrotthe original
Fit is the average pairing score against sauce, mushroom, pepper, lemon, mustard, onion, butter. Candidates are from the same food group and used in at least 100 recipes.
