Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that browns the apple and onion, adding richness and a toasted flavour to the base.
- Flour
- Thickens the stock into a smooth sauce as it cooks with the curry powder.
- Curry powder
- Supplies the spiced aroma and flavour that define the dish.
- Fish stock
- Forms the liquid of the sauce and carries the flavours during the slow simmer.
- Apple
- Adds natural sweetness and body that softens into the sauce.
- Lemon juice or vinegar
- Adds acidity that brightens the sauce and balances the sweetness and spice.
The step that matters
Gradually add the fish stock, skimming when boiling.. Adding stock slowly into the flour and curry mixture keeps it smooth without lumps, since flour clumps when hit with liquid all at once. Skimming removes foam and impurities that would cloud the sauce.
Swap the apple
How well each one fits the dish's main ingredients (fish, butter, onion, flour, lemon, pepper, rice):
- Limefits better
- Coconutfits better
- Avocadofits better
- Applethe original
Fit is the average pairing score against fish, butter, onion, flour, lemon, pepper, rice. Candidates are from the same food group and used in at least 100 recipes.
