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 ↓
Sole, Curried
Ingredients
Directions
Prepare the fish
Fillet the soles, then cut each fillet into 4 or 5 pieces.
Skin and clean the fish, cutting each fish into 3 or 4 pieces with bones in.
Rub the fish with curry powder and dredge it with a little flour.
Fry the fish in hot fat for 2–3 minutes, but do not cook fully.
Make the sauce
Mince the onions and sour apple.
Fry the mixture in hot fat until soft.
Pass the mixture through a sieve.
Mix the sifted mixture with the pulp, curry paste, curry powder, and ground rice.
Gradually add the stock.
Boil until the sauce is thick and smooth.
Finish and serve
Prepare warm curry sauce to cover the fish.
Carefully lay the fried fish in the sauce.
Let it simmer gently for about 10 minutes until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soles
- Forms the main body of the dish, cooked gently in the sauce until flaky.
- Onions
- Softened by frying, they add sweetness and body to the sauce base.
- Sour apple
- Adds acidity and body, balancing the richness of the curry sauce.
- Ground rice
- Thickens the sauce as it cooks, giving it a smooth, stable body.
- Flour
- Light dusting helps the fish brown in the hot fat and keeps its surface set.
- Stock
- Forms the liquid base of the sauce, carrying the curry flavour.
The step that matters
Fry the fish only briefly before simmering. Frying for just 2–3 minutes sets the coating and surface while the flesh stays tender. Cooking it fully at this point would leave it dry and firm before it finishes gently in the sauce.
Swap the apple
How well each one fits the dish's main ingredients (flour, onion, rice):
- Avocadofits better
- Coconutfits better
- Raisinfits better
- Applethe original
Fit is the average pairing score against flour, onion, rice. Candidates are from the same food group and used in at least 100 recipes.
