Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Curried Fish
Ingredients
Directions
Make the sauce
In a pan, brown the sliced apple and onion in the butter.
Stir in the flour and curry powder, then gradually add the fish stock.
Skim when boiling and simmer slowly for 30 minutes.

Finish and serve

Serve the curried fish on a dish with a border of cooked rice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that carries the curry spices and helps the apple and onion brown.
- Flour
- Thickens the stock into a smooth, lightly bodied sauce.
- Curry powder
- Provides the main spiced aroma and flavour of the sauce.
- Apple
- Adds natural sweetness and body to the sauce as it softens.
- White fish
- Main protein, cooked gently in the sauce until heated through.
The step that matters
Skim when boiling and simmer slowly for 30 minutes. Skimming removes foam and impurities that would cloud the sauce, and a slow simmer lets the apple and onion soften and the flavours blend without scorching the flour-thickened base.
Swap the apple
How well each one fits the dish's main ingredients (fish, butter, onion, flour, lemon, pepper, rice):
- Limefits better
- Coconutfits better
- Avocadofits better
- Applethe original
Fit is the average pairing score against fish, butter, onion, flour, lemon, pepper, rice. Candidates are from the same food group and used in at least 100 recipes.
