Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main savoury flavour and the bulk of the filling.
- Potatoes
- Add starch and body, binding the fish and giving the balls a soft interior.
- Eggs
- Bind the mixture together and help it hold its shape while frying.
- Butter
- Adds richness and fat, keeping the interior moist and tender.
- Flour
- Dry coating that helps the outside brown and form a crisp crust when fried.
The step that matters
Frying the balls in hot fat. If the fat is not hot enough, the balls absorb grease and turn heavy instead of forming a crisp, golden crust. Turning them gently keeps the delicate shapes from breaking apart.
