Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod fish
- Provides the main flavour and bulk of the fish balls.
- Potatoes
- Add body and starch that help the balls hold together.
- Eggs
- Bind the mixture so it holds its shape while frying.
- Butter
- Adds richness and a softer, moister texture to the mixture.
The step that matters
Frying in hot lard. If the lard is not hot enough, the balls absorb grease and turn heavy and soggy. Hot fat sets the outside quickly and browns it, keeping the inside tender.
Swap the potato
