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 sweetness and a savory base for the curry.
- Butter
- Carries the heat and browns the onion, adding richness to the sauce.
- Curry powder
- Supplies the spices that give the dish its aroma and flavor.
- Cooked chicken
- Provides the protein; it is already cooked, so it only needs to heat through.
- Flour
- Thickens the mixture as it cooks in the fat and juices.
The step that matters
Sprinkle flour over the mixture. Flour clumps if added to a dry or very hot pan without enough fat to coat it. Stirring well as it goes in helps it dissolve evenly and thicken the sauce smoothly rather than leaving lumps.
Swap the onion
How well each one fits the dish's main ingredients (butter, chicken, flour):
- Leekfits better
- Potatofits better
- Shallotfits about as well
- Onionthe original
Fit is the average pairing score against butter, chicken, flour. Candidates are from the same food group and used in at least 100 recipes.
