Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Duckling Pot Roast
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Braise
Place a thin strip of bacon and mixed whole spice in a shallow crock.
Add the ducklings and enough hot water or soup-stock to come halfway up the birds.
Add celery and parsley, then place a strip of bacon over each duckling.
Cover the crock and bake in a 350°F (175°C) oven for 2 hours.
Make the sauce
Remove the ducklings from the crock.
Strain the sauce, reducing it by one-third over heat.
Stir in dark wine.
Thicken the sauce with brown flour, simmering for 15 minutes.
Add lemon juice.
Optionally, boil down some sauce until thick as cream for glazing the ducklings.
Serve
Serve with the ducklings.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ducklings
- Provide the main meat, which becomes tender during the long, moist braise.
- Bacon
- Adds fat and savory flavor that bastes the birds as they cook.
- Dark wine
- Adds acidity and depth of flavor to the reduced sauce.
- Brown flour
- Thickens the sauce so it clings to the ducklings.
- Lemon juice
- Adds acidity that brightens the rich sauce.
The step that matters
Thickening the sauce with brown flour. Flour must be simmered long enough to cook out its raw starch taste and to thicken evenly. Adding it to hot liquid without stirring can cause lumps, so whisk well and keep it simmering.
Swap the celery
How well each one fits the dish's main ingredients (parsley, wine, flour, lemon):
- Thymefits better
- Tarragonfits better
- Marjoramfits better
- Celerythe original
Fit is the average pairing score against parsley, wine, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
