Why it works: Turnip and arrowroot share more aroma than cooks usually use. They rank in the top 1% of all ingredient pairs, and cooks put them together in 64 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Duck with Turnips
Ingredients
Directions
Prepare the duck
Remove the insides, singe, and truss the duck with its feet tucked behind it.
Make a roux in a pan and brown the duck in it.
Stir in the broth and season with salt, pepper, and bay leaf.
Turn the duck until the liquid boils, then add parsley and chives.
Cook the turnips
In another pan, fry sliced turnips in butter until light brown, then drain.
Add the turnips to the duck when it is three-quarters cooked.
Stew and finish
Stew slowly until the duck is fully cooked.
Thicken the gravy with arrowroot or flour, season to taste, and boil.
Serve
Serve the duck surrounded by the turnips.
For a fancier presentation, boil turnips until tender, then mash with pepper, salt, sugar, and cream.
Heat the puree, thicken by evaporation, and spread it on the serving dish.
Place the browned duck on top and arrange the fried turnip slices around it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Duck
- Provides the main meat, which is slowly stewed until fully cooked and tender.
- Butter
- Adds richness and helps the sliced turnips brown lightly in the pan.
- Broth
- Forms the cooking liquid that the duck stews in and becomes the gravy.
- Turnips
- Add mild sweetness and a tender texture when fried or mashed.
- Cream
- Adds richness and smoothness to the mashed turnip puree.
- Arrowroot or flour
- Thickens the gravy so it coats the duck and turnips.
The step that matters
Thicken the gravy with arrowroot or flour, then boil. Starch granules swell and gelatinise only when heated to a boil, so the gravy thickens properly only if it is brought fully to the boil after the thickener is added.
Swap the arrowroot
How well each one fits the dish's main ingredients (butter, pepper, parsley, chive, turnip, sugar, cream):
- Leekfits better
- Shallotfits better
- Parsnipfits better
- Arrowrootthe original
Fit is the average pairing score against butter, pepper, parsley, chive, turnip, sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
