Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Forms the main protein, flaking into the curry as it cooks.
- Butter
- Carries the frying and browns the onion, adding richness to the sauce.
- Onion
- Softens and browns to build a sweet, savoury base for the sauce.
- Curry powder
- Provides the spiced aroma and flavour that defines the dish.
- Milk
- Adds creaminess and body to the curry sauce.
- Coconut
- Adds sweetness, fat and a mild coconut flavour to the sauce.
The step that matters
Boiling the curry before adding the fish. The sauce must simmer long enough for the spices and onion to develop flavour and thicken, since milk can scorch or separate if boiled too hard. Boiling is timed here, so keep the heat controlled.
Swap the onion
How well each one fits the dish's main ingredients (milk, lemon, butter, sugar, coconut):
- Sweet potatofits better
- Arrowrootfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against milk, lemon, butter, sugar, coconut. Candidates are from the same food group and used in at least 100 recipes.
