Why it works: Butter and coconut are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 3,467 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
Prepare
Shell the prawns and set them aside.
Make the curry
Melt the butter or fat in a stewpan and fry the onion without browning.
Add the curry powder and flour, and fry slowly for at least 20 minutes.
Add the stock, apple, coconut, and a little salt, then simmer gently for about 30 minutes.
Strain the mixture and return it to the stewpan.
Season to taste, add the lemon juice, and put in the prawns.
Heat until hot and serve with well-boiled rice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Prawns
- Provide the main protein, cooking gently in the sauce until just hot.
- Butter or good fat
- Fries the onion and spices, carrying their aroma and giving the sauce richness.
- Curry powder
- Supplies the spiced, aromatic flavour that defines the dish.
- Flour
- Cooked with the fat and curry powder to thicken the sauce.
- Sour apple
- Adds acidity and a fruity tang that balances the spices.
- Stock
- Forms the liquid base of the sauce, which simmers and thickens as it reduces.
The step that matters
Fry the curry powder and flour slowly. Frying the spices and flour gently in fat cooks out raw starch and toasts the spices for depth of flavour. Rushing this over high heat can scorch the flour and leave a bitter, raw taste.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, apple, coconut, lemon):
- Arrowrootfits better
- Sweet potatofits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against butter, flour, apple, coconut, lemon. Candidates are from the same food group and used in at least 100 recipes.
