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 ↓
Wild Duck
Ingredients
Directions
Prepare
Truss the duck by twisting each leg at the knuckle and resting the claws on each side of the breast, securing them with a skewer through the thighs and wings.
Rub the liver over the breast.
Roast and carve
Roast the duck until underdone.
Slice the breast without detaching the slices, catching the escaping gravy in a saucepan.
Make the sauce and serve
Add the piece of glaze to the saucepan and heat it.
Once hot, add the butter, port wine, coarsely-ground pepper, and lemon juice.
Shake over the heat until the butter melts.
Pour the sauce over the duck and serve when perfectly cold.

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, whose rich fat and juices flavour the dish.
- Glaze
- Adds concentrated savoury body and a glossy finish to the sauce.
- Butter
- Emulsifies into the pan juices, giving the sauce a smooth, glossy richness.
- Port wine
- Adds sweetness and depth of flavour to the sauce as it reduces.
- Lemon juice
- Adds acidity that brightens the rich fat and sweet port.
The step that matters
Shaking the butter into the hot sauce. Adding butter to hot liquid and swirling it in off the heat helps form a smooth emulsion; if the sauce is too hot or left to boil, the butter can separate and turn greasy.
