Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Duck with Orange-sauce
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 the duck
Pluck the duck.
Singe the duck.
Wipe the duck with a wet towel.
Draw the duck carefully.
Chop the liver finely.
Stuff and truss
Mix the chopped liver with the bacon, onion, parsley, salt, pepper, and orange rind.
Stuff the duck with the mixture.
Truss the duck in shape.
Tie a large thin slice of fat bacon over the breast.
Place the duck in a dripping pan.
Roast
Put the duck in a hot oven at 400°F (200°C) for 15 to 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Duck
- Forms the main body of the dish, providing the meat that the stuffing and sauce accompany.
- Fat bacon
- Adds fat that bastes the bird and keeps the meat moist as it roasts.
- Onion
- Adds aromatic sweetness and savoury depth to the stuffing as it softens with the fat.
- Orange rind
- Contributes bright citrus aroma and oils that flavour the stuffing and duck.
The step that matters
Put the duck in a hot oven at 400°F (200°C) for 15 to 20 minutes.. Duck has a thick layer of fat under the skin. A hot oven renders that fat so the skin crisps, while the meat stays juicy. Too cool an oven leaves the skin flabby and greasy.
Swap the orange
How well each one fits the dish's main ingredients (onion, parsley, pepper):
- Limefits better
- Lemonfits better
- Avocadofits better
- Orangethe original
Fit is the average pairing score against onion, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
