Why it works: Onion and celery are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 18,518 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Duck Roasted
Ingredients
Directions
Prepare the duck
Clean the duck with a wet cloth, then dry it with a dry cloth.
If the duck has a strong flavor, place an onion inside and parboil for 10 minutes.
Remove the onion and plunge the duck into cold water, then take it out immediately.
Roast
Stuff the duck and roast it like chicken.
Add a lump of butter to the dripping pan with hot water and baste frequently.
Serve
Carve the duck into thick pieces and serve with currant jelly and celery.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Duck
- The main protein, whose fat renders out and whose skin browns during roasting.
- Butter
- Adds fat and richness, and helps the dripping pan liquid brown and flavour the bird.
- Currant jelly
- Its sweetness and acidity balance the rich, fatty duck meat.
The step that matters
Plunge the duck into cold water and remove it at once. A brief cold dip after parboiling stops the cooking and firms the skin, which helps it crisp later. Leaving the duck in the water would cook the meat further and make the skin soft and loose.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (butter, currant, celery):
- Carrotfits better
- Potatofits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against butter, currant, celery. Candidates are from the same food group and used in at least 100 recipes.
