Why it works: Pepper and onion are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Stewed Ducks
Ingredients
Directions
Prepare the duck
Joint the duck as for fricassee and season with salt, pepper, and flour.
Brown and stew
Heat dripping in a frying pan and fry the sliced onion until light brown.
Remove the onion and add the duck to the pan, cooking for 10 minutes and turning it two or three times.
In a saucepan, place the cold stock or consommé and add the jointed duck.
Cover and stew slowly until the duck is tender.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Duck
- Provides the main protein, which becomes tender through slow, moist stewing.
- Flour
- Coats the duck pieces, helping them brown and thickening the cooking liquid slightly.
- Onion
- Browns in the dripping to add sweetness and savoury depth to the stew.
- Stock or consommé
- Forms the moist cooking liquid that gently softens the duck as it stews.
The step that matters
Stewing slowly until tender. Low, covered simmering lets tough connective tissue break down gradually. Rushing with high heat can leave the meat tough and dry while the liquid evaporates.
Swap the onion
How well each one fits the dish's main ingredients (flour, pepper):
- Arrowrootfits better
- Okrafits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
