Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Soften and brown to build the sweet, savory base of the sauce.
- Apple
- Adds natural sweetness and body that softens into the sauce as it cooks.
- Butter
- Carries the curry spices and adds richness while the onions brown.
- Curry powder
- Provides the main spiced aroma and flavor of the dish.
- Flour
- Thickens the gravy so the sauce clings to the chicken and rice.
- Gravy
- Forms the liquid base of the sauce and carries its savory flavor.
The step that matters
Frying the onions and apple until browned. Browning builds deep flavor through the Maillard reaction and caramelization. Pale, underbrowned onions give a flat, sweet-tasting sauce, so cook until they are truly golden brown before adding liquid.
Swap the onion
How well each one fits the dish's main ingredients (apple, butter, flour, sugar, pepper, lemon, rice):
- Capsicumfits better
- Arrowrootfits better
- Sweet potatofits better
- Onionthe original
Fit is the average pairing score against apple, butter, flour, sugar, pepper, lemon, rice. Candidates are from the same food group and used in at least 100 recipes.
