The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fowl
- Provides the main protein, which becomes tender during the gentle stew.
- Onions
- Soften and sweeten as they cook, forming the base flavour of the sauce.
- Butter and flour
- Form a roux that thickens the sauce to a coating consistency.
- Curry powder
- Supplies the spice blend that gives the dish its characteristic aroma and flavour.
- Gravy
- Adds liquid and savoury body that the sauce is built on.
The step that matters
Mix the butter and flour to thicken the sauce. Flour must be cooked in fat or stirred in well so it disperses without lumps; added raw or in clumps, it leaves the sauce pasty and uneven.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, lemon, pepper):
- Shallotfits better
- Arrowrootfits better
- Okrafits better
- Onionthe original
Fit is the average pairing score against butter, flour, lemon, pepper. Candidates are from the same food group and used in at least 100 recipes.
