Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt-codfish
- Provides the main savory flavor and the bulk of the fish filling.
- Mashed potatoes
- Binds the fish and adds softness and moisture to the interior.
- Egg
- Binds the mixture together and helps the crumb coating adhere.
- Butter
- Adds richness and fat, softening the mixture and adding flavor.
- Milk
- Moistens the potato mixture so it becomes smooth and easy to shape.
The step that matters
Beat the mixture thoroughly. Beating works the potato and fish into an even, cohesive paste. Under-mixing leaves loose pockets that make the balls crumble when shaped or fried.
Swap the potato
How well each one fits the dish's main ingredients (milk, butter, egg):
- Potatothe original
- Asparagusfits about as well
- Chivefits less well
- Leekfits less well
Fit is the average pairing score against milk, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
