Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt codfish
- Provides the main savoury fish flavour and the body of the mixture.
- Mashed potatoes
- Adds starch and moisture that bind the fish and keep the cakes tender.
- Butter
- Adds richness and fat that softens the mixture and carries flavour.
- Eggs
- Set when cooked, binding the mixture so the cakes hold their shape.
The step that matters
Scalding the codfish three times. Salt cod is very salty and firm; repeated soaking and scalding draws out salt and softens the flesh. Too little scalding leaves the cakes overly salty and tough.
