Why it works: Butter and flour 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 ↓
Curries
Ingredients
Directions
Prepare the curry
Melt the butter in a stewpan.
Add the meat and sliced onions; cook over medium heat until browned.
Pour in the broth and simmer for 20 minutes.
In a bowl, mix the curry powder, flour, and salt with a little cold water until smooth.
Add this mixture to the stewpan and stir until it boils.
Simmer for an additional 20 minutes.
Finish and serve
Just before serving, add lemon juice and melted butter.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fowls or rabbits
- Provide the main protein, which becomes tender during simmering and browns at the start.
- Onions
- Add sweetness and body as they soften and brown in the butter.
- Flour
- Thickens the sauce so it clings to the meat rather than running thin.
- Curry powder
- Supplies the warm, aromatic spice flavour that defines the dish.
- Butter
- Carries fat for browning and adds richness to the sauce.
The step that matters
Stirring in the flour and curry mixture. Flour mixed with cold water first prevents lumps; once added to hot liquid it must be stirred until it boils so the starch swells and thickens the sauce evenly.
Swap the lemon
How well each one fits the dish's main ingredients (butter, rabbit, onion, flour):

- Avocadofits about as well
- Lemonthe original
Fit is the average pairing score against butter, rabbit, onion, flour. Candidates are from the same food group and used in at least 100 recipes.
