Codfish Balls
Ingredients
Directions
Prepare the codfish and potatoes
Soak the codfish in cold water until freshened, changing the water as needed.
Pick the codfish into small bits.
Boil the potatoes until tender, then mash them while hot.
Shape and fry
Mix the codfish with the mashed potatoes, using two-thirds potatoes and one-third codfish.
Add plenty of butter to the mixture.
Form the mixture into balls.
Heat lard in a pan until hot, then fry the balls until golden brown.

What each ingredient does
- Codfish
- Provides the savory, salty fish flavor that defines the dish.
- Potatoes
- Bind the fish together and give the balls a soft, tender interior.
- Butter
- Adds richness and moisture to the mixture and enhances flavor.
- Lard
- Conducts heat for frying, browning the outside of the balls to a golden crust.
The step that matters
Frying the balls until golden brown. The lard must be hot before the balls go in; otherwise they absorb oil and turn greasy instead of forming a crisp, browned crust.
