Ingredients
Directions
Prepare the mixture
Break the fish into flakes and sieve the potatoes until fine.
Mix fish and potatoes, season with salt, cayenne, and essence of anchovy.
Add butter, milk, and beaten egg to form a stiff paste.

Coat and fry
Brush cakes with egg.
Coat cakes in bread crumbs, repeating the process twice.
Heat frying fat in a saucepan until it reaches a thin blue smoke.
Carefully place cakes in a frying basket without touching each other.
Fry cakes until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the cakes and gives them their flaky texture.
- Potatoes
- Bind the fish and add a soft, moist texture to the cakes.
- Butter
- Adds richness and fat, keeping the paste tender and flavourful.
- Egg
- Binds the paste together and forms a crust that helps the coating adhere.
- Bread crumbs
- Form a crisp outer coating that browns during frying.
The step that matters
Frying the cakes in hot fat. If the fat is not hot enough, the coating absorbs oil and turns greasy instead of crisp. Crowding the basket drops the fat temperature and makes the cakes steam rather than brown, so they should be placed without touching.
