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
Keep the wild duck for several days before dressing if the weather is cold.
Optionally, parboil the duck with a small peeled carrot or onion to reduce fishy flavor before roasting.
Roast
Preheat the oven to 400°F (200°C).
Bake the duck for 5-10 minutes without basting to retain the gravy.
Baste frequently with butter and water for 30-40 minutes until cooked.
Make the sauce
Combine Worcestershire sauce, mushroom catsup, salt, cayenne pepper, and lemon juice in a small saucepan.
Heat the sauce, stir in prepared mustard, and pour 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 main meat, which is roasted until cooked through.
- 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 sauce.
- Prepared mustard
- Adds sharp flavor and a little tang to the finished sauce.
The step that matters
Withhold basting during the first roasting stage. Skipping basting at the start lets the skin set and the juices concentrate, which helps retain the gravy. Frequent basting later adds moisture and browning as the duck finishes cooking.
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.
