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 onions until nicely browned.
Transfer the fish and onions to a stewpan, add the stock and thickening, and simmer for 10 minutes.
Finish and serve
Stir the curry powder into the cream, then add it along with the seasoning to the stewpan.
Bring to a boil and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Forms the main body of the dish, flaking into tender pieces as it cooks.
- Butter
- Fat for frying that browns the fish and onions and adds richness.
- Onion
- Softens and browns in the butter, adding sweetness and savoury depth.
- White stock
- Liquid that forms the sauce base and carries the curry flavour.
- Flour
- Thickens the stock into a smooth sauce when cooked with butter.
- Cream
- Adds richness and body, mellowing the curry powder in the sauce.
The step that matters
Bring to a boil and serve. Once the cream is in, boiling can cause it to separate or curdle, and it can thicken unevenly. Keep the heat controlled so the sauce stays smooth.
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.
