Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Provides the main protein, which softens and flakes as it stews in the curry.
- Butter
- Carries the curry powder's aroma and adds richness to the sauce.
- Chopped onions
- Soften as they cook, adding sweetness and body to the sauce.
- Curry powder
- Supplies the spice flavour and aroma that defines the dish.
The step that matters
Stir in the curry powder and stew a little longer. Curry powder contains fat-soluble aromatic compounds that bloom when briefly cooked in hot butter. Stewing a little longer helps mellow the raw spice taste, but overcooking can scorch it and make the dish bitter.
Swap the onion
How well each one fits the dish's main ingredients (fish, butter, pepper, rice):
- Potatofits better
- Capsicumfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against fish, butter, pepper, rice. Candidates are from the same food group and used in at least 100 recipes.
