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 ↓

Ingredients
Directions
Mix the curry powder and flour with a little water to form a smooth paste.
Stir the paste into the stock or gravy soup and add the fried onion.
Simmer in a stewpan until it thickens.
Add the prawns and simmer for 15 minutes, stirring occasionally to avoid breaking them.
Add the butter and vinegar, then simmer for an additional 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Curry powder
- Provides the spiced flavour that defines the dish.
- Flour
- Thickens the sauce as it simmers, giving it body.
- Stock or gravy soup
- Forms the liquid base of the sauce.
- Prawns
- Provide the main protein and delicate sweet flavour.
- Butter
- Adds richness and a silky mouthfeel to the sauce.
- Vinegar
- Adds acidity that brightens the flavour of the sauce.
The step that matters
Stirring the prawns gently while they simmer. Prawns are delicate and their proteins toughen and break apart with vigorous handling or overcooking, so gentle stirring keeps them intact and tender.
Swap the onion
How well each one fits the dish's main ingredients (flour, butter, vinegar):
- Shallotfits better
- Mustardfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against flour, butter, vinegar. Candidates are from the same food group and used in at least 100 recipes.
