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
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.
Make the sauce and serve
For the sauce, combine Worcestershire sauce, mushroom catsup, salt, cayenne pepper, and lemon juice in a small saucepan.
Heat the mixture, then stir in prepared mustard and pour into a hot gravy boat.
Serve on a very hot dish with a cut lemon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Wild duck
- Provides the main meat, which cooks through during roasting.
- Butter
- Adds fat and richness, and helps the skin brown while basting.
- Worcestershire sauce
- Adds savoury, tangy depth to the sauce.
- Mushroom catsup
- Adds concentrated savoury umami flavour to the sauce.
- Prepared mustard
- Adds sharpness and a mild acidic bite to the finished sauce.
The step that matters
Baste only after the initial roast. Basting too early, before the surface has set, can wash off seasoning and keep the skin from browning. Waiting keeps the gravy in the pan for the basting stage that follows.
Swap the mustard
How well each one fits the dish's main ingredients (butter, sauce, mushroom, pepper, lemon):

- 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.
