Why it works: Onion and rice are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 10,433 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
How to Curry Fish
Ingredients
Directions
Make the gravy
Make a rich fish gravy using fish bones and some flesh.
Fry the onions in butter and add them to the gravy.
Stir in the curry powder and a piece of butter rolled in flour.
Cook the fish
Half-fry the fish as if for stewing, then place it in a stew pan.
Let the fish stew slowly over low heat until cooked through.
Prepare the rice
Prepare the rice by boiling it gently until done, then drain.
Place the saucepan with rice on the stove or fire until grains separate.

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
- Fish
- Provides the main protein and flavour, with bones and flesh enriching the gravy.
- Onions
- Add sweetness and body to the gravy as they soften and brown in butter.
- Butter
- Carries the onion flavour and adds richness to the gravy.
- Curry powder
- Supplies the spice aroma and flavour that define the dish.
- Flour
- Thickens the gravy so it coats the fish and rice.
The step that matters
Half-fry the fish before stewing. Searing the surface firms the flesh so it holds together during slow stewing instead of breaking apart in the gravy.
Swap the onion
How well each one fits the dish's main ingredients (fish, butter, flour, rice):
- Leekfits better
- Shallotfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against fish, butter, flour, rice. Candidates are from the same food group and used in at least 100 recipes.
