Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salted cod fish
- Provides the main savory flavor and the fish base of the balls.
- Potatoes
- Add starch and body, binding the mixture and keeping the balls soft inside.
- Egg
- Binds the mashed mixture together so the balls hold their shape while frying.
- Butter
- Adds richness and moisture, softening the mixture.
The step that matters
Beat the mixture until light. Beating incorporates air and evenly distributes the egg and butter, giving a lighter texture. Undersoaked or overworked mixtures can turn dense or gummy, so the consistency should be smooth before frying.
Swap the potato
