Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt fish
- Provides the main savory flavour and salty character of the balls.
- Potatoes
- Supply starch and bulk, giving the mixture a soft, mashable body.
- Egg
- Acts as a binder that helps the mashed mixture hold its shape.
- Butter
- Adds fat for richness and a softer, smoother texture.
The step that matters
Mashing the boiled mixture. If the potatoes are not fully tender or are left lumpy, the mixture will be uneven and hard to shape into balls. Mashing while still warm helps the starch blend smoothly with the egg and butter so the balls hold together.
