Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Prepared fish
- Provides the main flavour and the bulk of the filling.
- Mashed potatoes
- Adds body and moisture, helping the balls hold together while frying.
- Egg
- Binds the mixture so the balls keep their shape.
- Butter
- Adds richness and flavour to the mixture.
The step that matters
Shaping and frying the balls. The mixture is soft, so it should be well combined and shaped firmly before frying. Loose balls can break apart in the hot lard, and frying in hot fat browns the surface and sets the outside.
