Fish Balls
Ingredients
Directions
Prepare the mixture
Boil the potatoes until tender, then drain and place in a bowl.
Mash the potatoes until light and fine.
Mix the mashed potatoes thoroughly with the chopped salt-fish.
Taste and add salt if needed.
Mix in the butter and egg if using.
For moister balls, add milk to the mixture before shaping.
Shape and fry
Shape the mixture into round balls about the size of an egg.
Heat oil in a pan and fry the balls until they are a handsome brown, about 5 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt-fish
- Supplies the main salty, savoury flavour of the balls.
- Potatoes
- Form the starchy base that holds the balls together and gives them a soft interior.
- Butter
- Adds fat for richness and a softer, more tender texture.
- Egg
- Binds the mixture so the balls hold their shape while frying.
- Milk
- Adds moisture, keeping the inside of the balls softer.
The step that matters
Frying the balls until handsome brown. Frying in hot oil browns the outside through the Maillard reaction, creating flavour and a crisp crust. If the oil is too cool, the balls absorb grease and turn soggy before browning.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
