Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Provides the main flavour and bulk of the fish balls.
- Raw potatoes
- Adds body and starch that helps the balls hold together.
- Eggs
- Bind the mixture so the balls hold their shape while frying.
- Butter
- Adds richness and moisture to the mixture.
The step that matters
Drop spoonfuls of the mixture into a kettle of hot lard. The fat must be hot enough to set the outside quickly. If it is too cool, the balls absorb grease and turn heavy and soggy instead of crisp and golden.
