Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
To Curry Fish
Ingredients
Directions
Make the curry
Lightly brown the fish pieces.
Combine beef stock and finely chopped onion in a saucepan and boil until it becomes a pulp.
Mix in 2 teaspoons of curry powder until smooth.
Add the fish to the saucepan and heat until thoroughly hot.
Serve
Carefully lift out the fish and pour the sauce over it in a serving dish.
Serve with a wall of rice. Optionally, infuse mashed potatoes or mashed apples into the curry for added flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef stock
- Forms the liquid base of the sauce and carries the curry flavor.
- Onion
- Breaks down into a pulp that thickens the sauce and adds sweetness.
- Curry powder
- Supplies the spice and aroma that define the dish.
- Fish
- Provides the main protein; browning first adds colour and savoury flavor.
The step that matters
Boiling the stock and onion until pulpy. The onion must break down fully to thicken the sauce; if it stays in chunks the sauce will be thin and grainy. Curry powder added after a long boil can also taste raw or dull, so stir it in until smooth.
Swap the potato
The recipe marks potato as optional. How well each one fits the dish's main ingredients (fish, beef, onion, rice, apple):
- Potatothe original
- Tomatofits about as well
- Carrotfits less well
- Capsicumfits less well
Fit is the average pairing score against fish, beef, onion, rice, apple. Candidates are from the same food group and used in at least 100 recipes.
