Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold cooked fish
- Provides the main flavour and the bulk of the balls.
- Cold mashed potatoes
- Binds the fish together and adds softness and body to the mixture.
- Egg
- Helps bind the mixture so the balls hold their shape while frying.
- Melted butter
- Adds richness and moisture to the mixture.
The step that matters
Fry in boiling fat or lard until brown. The fat must be hot enough to brown the outside quickly. If it is too cool, the balls absorb more fat, become greasy, and can break apart before the outside sets.
Swap the potato
How well each one fits the dish's main ingredients (fish, butter, egg):
- Asparagusfits about as well
