What each ingredient does
- Codfish
- Provides the salty, savory flavor that defines the dish.
- Potatoes
- Starch bulks the mixture and binds it so the balls hold their shape.
- Butter
- Adds richness and moisture to the mashed mixture.
- Lard
- Conducts heat for frying, browning the outside to a golden crust.
The step that matters
Mixing the potatoes with the codfish while still hot. Hot potatoes mash and blend smoothly and take up the fish evenly. Once cool, the starch sets firmer and the mixture becomes stiff and harder to form into balls.
