Why it works: Flour and lemon are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 30,404 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Curried Soles
Ingredients
Directions
Prepare
Slice the onion thinly.
Fry the sliced onion gently in a small amount of butter until browned.
Drain the fried onion on a sieve.
In a stewpan, mix the curry powder, salt, and flour.
Remove the flesh from the soles into fillets or use heads and tails from small soles.
Divide each fish into halves without boning.
Rub half of the curry powder mixture onto the soles.
Fry the soles quickly and lightly.
Place the fried soles on the drained onion in the stewpan.
Make the curry
Add boiling water or broth to the pan. Shake the pan and boil for one minute.
When it begins to simmer, stir in the remaining curry powder. Add a few tablespoons of cold broth or water.
Stew the curry gently for 15 to 20 minutes.
Add lemon juice or chili vinegar.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sole
- Forms the main body of the dish, cooking through gently in the curry sauce.
- Onion
- Browned slices add sweetness and savory depth to the sauce base.
- Curry powder
- Supplies the main spiced flavor and aroma of the dish.
- Flour
- Thickens the curry sauce so it clings to the fish.
- Lemon juice or chili vinegar
- Adds acidity that brightens the rich, spiced curry.
The step that matters
Frying the soles quickly and lightly. Fish flesh is delicate and toughens or breaks apart with overcooking. A brief, light fry sets the surface so the fish holds its shape while it finishes gently in the simmering curry.
Swap the onion
How well each one fits the dish's main ingredients (flour, lemon):
- Arrowrootfits better

- Onionthe original
Fit is the average pairing score against flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
