Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main savory flavor and bulk of the balls.
- Egg
- Binds the mashed potato and fish together so the balls hold their shape.
- Potatoes
- Add starch and body, giving the mixture a soft, cohesive texture.
- Butter
- Adds richness and flavor to the mashed mixture.
The step that matters
Shape the mixture into tablespoon-sized balls. The mixture must be firm enough to hold its shape. Too much moisture from the potatoes or egg can make the balls slump and fall apart when they hit the hot fat.
Swap the potato
How well each one fits the dish's main ingredients (egg, butter):
- Asparagusfits better
- Chivefits better
- Leekfits about as well
- Potatothe original
Fit is the average pairing score against egg, butter. Candidates are from the same food group and used in at least 100 recipes.
