Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod-fish
- Provides the main protein, which firms and flakes as it browns in the pan.
- Onions
- Soften and turn sweet as they cook, forming the savoury base of the dish.
- Curry powder
- Adds aroma and warm spice flavour, which blooms when mixed into the hot pan.
The step that matters
Sprinkle curry powder over the fish and onions, mixing well. Spices need some heat and fat to release their aroma, but scorch and turn bitter if left too long over high heat. Mixing evenly prevents clumps and burnt patches.
Swap the onion
How well each one fits the dish's main ingredients (fish, butter):
- Potatofits better
- Leekfits about as well
- Onionthe original
- Asparagusfits about as well
Fit is the average pairing score against fish, butter. Candidates are from the same food group and used in at least 100 recipes.
