Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Curry of Cold Meat
Ingredients
Directions
Prepare the base
Peel and slice the apple and onion.
Melt the butter in a frying pan and fry the apple and onion until light brown.
Mix the curry powder, mulligatawny paste, corn flour, and salt with a little cold water to form a smooth paste.
Add the paste to the frying pan and stir in the gravy until it boils.
Let the mixture simmer for 10 minutes.
Finish and serve
Strain into a clean saucepan, cut the cold meat into small pieces, and add to the curry gravy.
Simmer gently for 30 minutes.
Serve on a dish with well-boiled rice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold meat
- Provides the main body of the dish, and is warmed through in the curry gravy.
- Apple
- Adds mild sweetness and softens into the sauce as it cooks.
- Onion
- Browns in the butter, building savoury depth and sweetness for the curry base.
- Curry powder
- Supplies the spiced aroma and flavour that define the dish.
- Corn flour
- Thickens the gravy into a smooth sauce as it heats.
- Butter
- Carries the frying of the apple and onion and adds richness.
The step that matters
Stirring the cornflour paste into the gravy. Cornflour must be mixed smoothly with cold water first, then stirred into hot liquid and brought to a boil. Starch added dry or unmixed clumps and stays lumpy, while boiling is needed for the starch to swell and thicken the sauce.
Swap the apple
How well each one fits the dish's main ingredients (meat, onion, corn, flour, butter):
- Avocadofits better
- Coconutfits better
- Raisinfits better
- Applethe original
Fit is the average pairing score against meat, onion, corn, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
