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).
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.
Make the sauce
For the sauce, combine Worcestershire sauce, mushroom catsup, salt, cayenne pepper, and lemon juice in a small saucepan.
Heat the mixture, then remove from heat and stir in prepared mustard.
Pour the sauce into a hot gravy boat.
Serve
Serve on a very hot dish with a cut lemon.
If using teal, serve each on a slice of toast roasted before the fire.

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, which is cooked through by dry roasting and basting.
- Butter
- Adds fat and richness, and browns the skin while basting.
- Worcestershire sauce
- Adds savoury, tangy depth to the sauce.
- Lemon juice
- Adds acidity that brightens the sauce and cuts the richness of the fat.
The step that matters
Bake without basting at first. Basting too early can wash the surface and cool the oven-heated skin, so the duck browns unevenly and loses the gravy it holds. Wait the short initial period before basting frequently.
Swap the mustard
How well each one fits the dish's main ingredients (butter, sauce, mushroom, pepper, lemon):
- Shallotfits better
- Capsicumfits better
- Spinachfits better
- Mustardthe original
Fit is the average pairing score against butter, sauce, mushroom, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
