Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw fish
- Provides the main flavour and the bulk of the mixture.
- Potatoes
- Adds starch and body, helping the mixture hold together and stay light.
- Eggs
- Bind the mixture so the balls keep their shape while frying.
- Butter
- Adds fat and richness, softening the mixture and improving flavour.
The step that matters
Draining the water after boiling. Excess water left in the fish and potatoes dilutes the mixture and makes it soggy, so the balls may fall apart or absorb too much fat when fried.
