Why it works: Onion and flour are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 32,460 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Curry of Baked Fish
Ingredients
Directions
Make the curry sauce
Heat lard in a frying pan.
Add minced onion and fry until brown.
Stir in hot water or broth, salt, and curry powder.
If desired, strain the sauce and add wet flour to reduce pungency.
Finish with fish
Add flaked fish and let it absorb the curry on low heat for 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lard
- Fat that carries flavour and gives the onion a rich base for frying.
- Onion
- Frying until brown builds sweetness and savoury depth in the sauce.
- Curry powder
- Provides the spice aroma and flavour that define the dish.
- Wet flour
- Thickens the sauce and softens the sharp edge of the curry.
- Baked fish
- Absorbs the curry sauce as it sits on low heat, carrying its flavour.
The step that matters
Frying the onion until brown. Browning the onion in lard develops sweet, savoury flavours that a pale, soft onion cannot give. Stopping too early leaves the sauce tasting raw and flat.
Swap the onion
How well each one fits the dish's main ingredients (flour, fish):
- Arrowrootfits better
- Shallotfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against flour, fish. Candidates are from the same food group and used in at least 100 recipes.
