Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Modern Cookery
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare and roast
Truss the duck firmly.
Roast the duck halfway at 400°F (200°C).
Stew
In a stewpan, add the duck as it comes off the spit.
Brown the duck in some thickening.
Cover the duck partially with boiling gravy.
Turn the duck when it is partially cooked.
Stew the duck for 1 to 1.25 hours until well cooked.
Finish
In the last 30 minutes, add the carrots, green onions, parsley, and shallots to the stew.

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, and its fat enriches the broth as it stews.
- Boiling gravy
- Forms the liquid that gently cooks the duck and becomes the sauce.
- Carrots
- Add sweetness and colour to the stew as they soften.
- Shallots
- Add a mild, sweet aroma that mellows during stewing.
- Green onions
- Contribute fresh aroma that softens into the stew.
- Butter
- Provides fat for frying, helping the duck brown richly.
The step that matters
Turn the duck when it is partially cooked. The gravy only covers part of the bird, so turning exposes the rest to the liquid and heat. This helps the duck cook evenly and stay moist rather than drying on top.
Swap the onion
How well each one fits the dish's main ingredients (carrot, parsley, shallot, butter):
- Leekfits better
- Parsnipfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against carrot, parsley, shallot, butter. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
