What each ingredient does
- Codfish
- Provides the main savory flavor and firm, flaky body of the balls.
- Potatoes
- Bind the fish together and give the balls a soft, tender interior.
- Butter
- Adds richness and moisture to the mashed mixture.
- Lard
- Conducts heat for frying and browns the outside of the balls.
The step that matters
Fry the balls until golden brown. Lard must be hot before the balls go in, or they absorb fat and turn greasy. Browning from frying forms a crisp surface through the Maillard reaction, so the balls should be turned until evenly colored.
