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 and roast
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 and heat the sauce.
Remove from heat and stir in prepared mustard.
Serve
Serve the duck on a hot dish with the sauce in a hot gravy boat and a cut lemon.
Optionally, parboil the duck with a small peeled carrot or onion to reduce fishy flavor before roasting.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Wild duck
- Provides the lean meat that is roasted, with its texture set by gentle heat.
- Butter
- Adds fat that carries flavour and helps the skin brown while basting.
- Lemon juice
- Adds acidity that brightens the rich, gamey flavour of the sauce.
- Worcestershire sauce
- Adds savoury depth and a tangy, salty note to the sauce.
The step that matters
Baste, then stop at done. Wild duck is very lean and dries out quickly. Basting with fat helps keep the surface moist and browned, while overcooking toughens the protein and drives off moisture. Check for doneness at the end of the time range.
Swap the carrot
The recipe marks carrot as optional. How well each one fits the dish's main ingredients (butter, sauce, mushroom, pepper, lemon, mustard, onion):
- Shallotfits better
- Horseradishfits better
- Chivefits better
- Carrotthe original
Fit is the average pairing score against butter, sauce, mushroom, pepper, lemon, mustard, onion. Candidates are from the same food group and used in at least 100 recipes.
