Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken
- Provides the protein and meat that becomes tender during the long simmer.
- Butter
- Carries the curry powder's fat-soluble flavor and helps brown the onions.
- Onions
- Browning them builds sweetness and a savory base for the sauce.
- Curry powder
- Supplies the spice blend that gives the dish its characteristic aroma and flavor.
- Tomatoes
- Add acidity and moisture that help form the simmering sauce.
- Milk
- Adds richness and softens the sharpness of the spices and tomatoes.
The step that matters
Cooking the onions until browned. Onions that are only softened, not browned, leave the curry pale and less sweet. Browning caramelizes their sugars and builds the deep flavor the sauce depends on.
Swap the onion
How well each one fits the dish's main ingredients (chicken, butter, tomato, pepper, milk):
- Capsicumfits better
- Potatofits better
- Onionthe original
- Asparagusfits about as well
