Why it works: Shallot and flour match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 2,081 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Add butter, sliced shallots, and apple to the saucepan. Cook until browned.
Stir in flour, curry powder, salt, and cayenne pepper.
Add stock and let it boil for a few minutes.
Return the cod to the saucepan to warm up.

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
- Cod
- Provides the flaky, fish-based body of the dish, already cooked and warmed through again.
- Shallots
- Soften and brown in butter, adding mild sweetness and savoury depth to the sauce.
- Apple
- Softens and browns with the shallots, adding a touch of sweetness that balances the curry.
- Flour
- Thickens the stock into a smooth sauce that coats the fish.
- Curry powder
- Provides the main spiced aroma and flavour of the dish.
The step that matters
Add the stock and let it boil. Flour needs to be cooked in the hot fat and liquid for a few minutes to thicken fully and lose its raw taste, so the sauce should be boiled gently rather than just warmed.
Swap the apple
How well each one fits the dish's main ingredients (butter, shallot, flour, pepper):
- Lemonfits better
- Limefits better
- Avocadofits better
- Applethe original
Fit is the average pairing score against butter, shallot, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
