Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Starch that mashes into a soft base that holds the balls together.
- Codfish
- Flaked protein that provides the main savoury flavour and body.
- Egg
- Binds the mashed mixture so the balls hold their shape while frying.
- Butter
- Adds richness and moisture to the mashed mixture.
- Lard
- Heats the balls evenly and browns their outside as they fry.
The step that matters
Fry in hot lard. If the lard is not hot enough, the balls absorb grease and turn heavy and soggy instead of forming a crisp golden crust. Frying at a steady high heat seals the surface quickly.
Swap the potato
