Why it works: Watercress and onion match in chemistry and in kitchens. They rank in the top 9% of all ingredient pairs, and cooks put them together in 533 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Duck, Wild, with Port Wine
Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Roast the duck
Truss the duck.
Cover the duck with the strip of fat pork and the sheet of paper.
Cook the duck in a brisk oven at 400°F (200°C) for 20 minutes.
Make the sauce
Fry the onion in butter with the bouquet garni.
Moisten the sauce with the stock and reduce to a demi-glace.
Boil the sauce and skim.
Strain the sauce.
Add the red currant jelly and port wine to the sauce.
Bring the sauce to a boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Wild duck
- Provides the meat that is roasted and served with the sauce.
- Port wine
- Adds sweetness and depth of flavour to the reduced sauce.
- Red currant jelly
- Adds sweetness and a fruity note that balances the sauce.
- Stock
- Forms the liquid base that reduces into a concentrated demi-glace.
- Butter
- Fat that softens the onion and carries the flavour of the aromatics.
- Onion
- Contributes savoury aroma and body to the sauce base.
The step that matters
Bring the sauce to a boil. Boiling after adding the port and jelly can over-concentrate or dull the flavour; the sauce should be heated just enough to combine and serve hot.
