Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Cod, Curried
Ingredients
Directions
Cook the fish
Flake the fish and fry it in butter with the sliced onions until nicely browned.
Transfer the fish and onions to a stewpan, add the white stock and thickening, and simmer for 10 minutes.
Finish and serve
Stir the curry powder into the cream, then add it along with salt and cayenne to the stewpan.
Bring to a boil and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Provides the flaked protein that forms the body of the dish.
- Butter
- Carries the frying and adds richness and browning to the fish and onion.
- Onion
- Softens and browns in butter, adding sweetness and savoury depth to the sauce.
- Flour
- Thickens the white stock into a smooth sauce that coats the fish.
- Cream
- Adds richness and a mellow body that tempers the curry powder.
- Curry powder
- Supplies the spiced aroma that defines the dish.
The step that matters
Brown the fish and onions before simmering. Browning in butter creates deeper flavour through the Maillard reaction. Pale frying gives a flatter, less savoury sauce once the stock is added.
Swap the onion
How well each one fits the dish's main ingredients (fish, butter, flour, cream, pepper):
- Potatofits better
- Leekfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against fish, butter, flour, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
