Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled fish
- Provides the main body and flavour of the balls.
- Mashed potato
- Adds bulk and softness, and helps the mixture hold together when shaped.
- Egg yolk
- Binds the mixture and adds richness to hold the balls together.
- Beaten egg
- Forms a coating that helps breadcrumbs stick and promotes even browning.
The step that matters
Fry in hot oil until golden brown. If the oil is not hot enough, the breadcrumb coating absorbs oil and turns greasy instead of crisping. Hot oil seals the crust quickly, so the balls brown evenly and stay less oily inside.
Swap the onion
How well each one fits the dish's main ingredients (fish, potato, pepper, egg, parsley):
