Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flathead fish
- Provides the main protein, which firms and flakes as it cooks in the sauce.
- Butter
- Adds fat and richness, carrying the curry spices so their flavour spreads through the sauce.
- All-purpose flour
- Thickens the milk-based sauce as its starch swells during boiling.
- Milk
- Forms the liquid base of the sauce and adds creaminess.
- Curry powder
- Supplies the spiced aroma and flavour that define the dish.
- Apple
- Adds mild sweetness and body that softens into the sauce as it cooks.
The step that matters
Boiling the sauce after adding the flour and milk. Flour only thickens fully when the starch granules swell in hot liquid, so the sauce must reach a boil and stay there. Stirring well prevents lumps and scorching on the base of the pan.
Swap the onion
How well each one fits the dish's main ingredients (fish, butter, apple, sugar, flour, milk):
- Potatofits better
- Sweet potatofits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against fish, butter, apple, sugar, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
