Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Bulk the mixture and, when mashed, give the balls a soft, light interior.
- Salt fish
- Provides the main savoury flavour and the flaked texture of the balls.
- Egg
- Binds the mashed mixture so the balls hold their shape while frying.
- Cream or milk
- Adds moisture and softness, keeping the mixture tender rather than dry.
- Butter
- Adds richness and flavour, and helps the surface brown in the pan.
The step that matters
Fry in plenty of hot fat. The fat must be hot enough to brown the outside quickly. If it is too cool, the balls absorb oil, turn greasy, and the centre cooks unevenly before the outside sets.
Swap the potato
