What each ingredient does
- Cod fish
- Provides the main protein and flaky body that forms the balls.
- Potatoes
- Starch binds the fish, giving the mixture a soft, cohesive texture when mashed.
- Butter
- Fat in the pan promotes browning and adds richness to the outside of the balls.
The step that matters
Mashing the potatoes while hot. Hot potatoes mash smoothly and blend evenly with the fish. Cooled potatoes turn stiff and gummy, which makes the mixture harder to bind and shape.
