What each ingredient does
- Salt codfish
- Supplies the salty, savory flavor that defines the dish.
- Potatoes
- Their starch becomes fluffy when mashed and holds the mixture together.
- Butter
- Adds fat for richness and a smoother, softer texture.
The step that matters
Drain the potatoes thoroughly. Excess water makes the mash wet and loose, so the mixture turns soft and sticky and is harder to shape and hold together when cooked.
