Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold beef
- Provides the main protein, which becomes tender during the simmer.
- Sour apple
- Adds tartness and body to the sauce as it breaks down.
- Curry powder
- Supplies the main spiced aroma and flavour of the curry.
- Flour
- Thickens the sauce as it cooks with the liquid.
- Bacon fat
- Carries the spices and adds savoury richness to the base.
- Lemon juice
- Adds acidity that brightens the finished curry.
The step that matters
Adding the water to the flour mixture. Adding liquid gradually while stirring keeps the flour smooth and lump-free, so the sauce thickens evenly instead of clumping.
Swap the apple
How well each one fits the dish's main ingredients (beef, onion, lemon, flour):
- Avocadofits better
- Limefits better
- Raisinfits better
- Applethe original
Fit is the average pairing score against beef, onion, lemon, flour. Candidates are from the same food group and used in at least 100 recipes.
