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 ↓
To Roast a Wild-duck
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Roast
Preheat the oven to 400°F (200°C).
Place the wild duck in the oven and roast for about 45 minutes, basting frequently with butter.
Serve
When ready to serve, pour beef gravy through the duck into the serving dish.
In a separate sauce tureen, serve hot port wine.
Make four cuts along the breast of the duck, sprinkle with salt and cayenne pepper.
Squeeze the juice of ½ lemon over the duck and pour the port wine over it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Wild duck
- Is the main protein, cooked by dry roasting in the oven.
- Butter
- Adds fat that carries heat and promotes browning on the duck skin while basting.
- Beef gravy
- Adds savoury moisture and rich meaty flavour to the carved duck.
- Port wine
- Adds sweetness and depth to the sauce served with the duck.
- Lemon juice
- Adds acidity that brightens the rich flavour of the duck.
The step that matters
Basting the duck during roasting. Wild duck is lean and can dry out in the oven. Frequent basting with butter adds fat and moisture to the surface, helping the skin brown and the meat stay tender.
