Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the mixture together and help the cakes hold their shape while frying.
- Potato
- Adds body and starch that helps the mixture hold together and stay moist.
- Left-over fish
- Provides the main flavour and the bulk of the cakes.
- Thick cream
- Adds moisture and richness, keeping the inside of the cakes tender.
- Onions
- Adds savoury flavour and moisture to the mixture.
The step that matters
Fry the balls in hot fat until golden brown. The fat must be hot enough to brown the outside quickly, so the cakes crisp and hold their shape before the soft interior breaks apart or absorbs excess oil.
Swap the onion
