Prepare
Flake the cold boiled cod into a bowl.
Add two-thirds as much hot mashed potatoes as fish.

Season with pepper.
Form and fry
Form the mixture into round cakes.
Fry the cakes in sweet beef drippings or clear sweet lard until brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Forms the main body and flavour of the cakes.
- Hot mashed potatoes
- Bind with the fish and add softness to the cake interior.
- Eggs
- Bind the mixture together so the cakes hold their shape.
- Butter
- Adds richness and moisture to the mixture.
- Milk
- Loosens the mixture into a smooth paste that is easy to shape.
The step that matters
Making the smooth paste. If the milk and egg are not mixed in evenly, the mixture can stay crumbly or wet in patches, so the cakes may fall apart or cook unevenly. A smooth, well-combined paste holds together during shaping and frying.
Swap the potato
How well each one fits the dish's main ingredients (butter, egg, milk, pepper, beef):
- Potatothe original
- Capsicumfits about as well
- Asparagusfits less well
- Tomatofits less well
Fit is the average pairing score against butter, egg, milk, pepper, beef. Candidates are from the same food group and used in at least 100 recipes.
