Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Provide the bulk and soft body that holds the fish balls together.
- Eggs
- Bind the mixture so the balls hold their shape while frying.
- Boiled codfish
- Supplies the main flavour and the flaky texture of the filling.
The step that matters
Dropping spoonfuls into hot lard. If the fat is not hot enough, the balls absorb grease and turn heavy. Hot fat sets the outside quickly, so the inside stays moist and the balls keep their shape.
Swap the potato
How well each one fits the dish's main ingredients (egg, butter):
- Asparagusfits better
