Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt fish
- Provides the savory, salty flavour that defines the fish balls.
- Potatoes
- Form the starchy base that mashes into a soft, cohesive mixture.
- Egg
- Binds the mashed mixture so the balls hold their shape when fried.
- Butter
- Adds richness and moisture to the mashed mixture.
The step that matters
Drop spoonfuls into a frying basket and fry in deep fat.. If the mixture is too wet or the fat is not hot enough, the balls can absorb oil and fall apart or turn greasy. Frying at proper heat sets the outside quickly so the inside stays tender.
Swap the potato
