Make the balls

What each ingredient does
- Codfish
- Provides the main savory flavor and the flaky texture of the balls.
- Potatoes
- Bind the fish together and give the balls a soft, tender body.
- Butter
- Adds richness and moisture to the mixture.
The step that matters
Repeat soaking the codfish until fresh. Salted cod must be soaked long enough to remove excess salt and rehydrate the flesh. Under-soaked fish makes the balls overly salty and firm, so tasting and changing the water until the fish is fresh matters for the final flavor.
