Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold meat
- Forms the bulk of the dish and supplies its main savoury flavour as it simmers.
- Onion
- Cooked gently until soft, it adds sweetness and body to the sauce.
- Curry powder
- Blooming it in fat releases its aromatic compounds, giving the dish its characteristic flavour.
- Flour
- Thickens the sauce as its starch absorbs liquid and swells during simmering.
- Stock
- Forms the liquid of the sauce and keeps the meat moist while it simmers.
- Lemon juice
- Its acidity brightens the flavour and balances the richness of the curry.
The step that matters
Mixing the flour into the fat and spices. Flour must be stirred evenly into the fat and spices before the stock goes in, otherwise it clumps and forms lumps that do not dissolve when the liquid is added.
Swap the apple
The recipe marks apple as optional. How well each one fits the dish's main ingredients (meat, onion, butter, flour, lemon):
- Avocadofits better
- Limefits better
- Coconutfits better
- Applethe original
Fit is the average pairing score against meat, onion, butter, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
