Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Browns in butter to build a sweet, savory base for the sauce.
- Butter
- Adds fat for browning the onion and cooking the chicken.
- Curry powder
- Provides the main spice flavor of the curry.
- Chicken
- Forms the main protein of the dish, cooked in the spiced sauce.
- Flour
- Thickens the sauce so it clings to the chicken.
The step that matters
Thicken the sauce with flour. Flour must be cooked in the fat and liquid to avoid a raw, pasty taste and lumps. Stirring it in evenly lets starch swell and thicken the sauce smoothly.
Swap the onion
How well each one fits the dish's main ingredients (butter, chicken, pepper, flour):
- Capsicumfits better
- Potatofits better
- Leekfits about as well
- Onionthe original
Fit is the average pairing score against butter, chicken, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
