Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked fish
- Forms the body of the cakes and gives them their main flavour.
- Mashed potatoes
- Binds the fish together and keeps the cakes moist and soft inside.
- Egg
- Coats the cakes so the breadcrumbs stick and help them brown.
- Butter
- Adds richness and moisture to the fish and potato mixture.
The step that matters
Fry in hot dripping until nicely browned. The cakes are already cooked through, so frying is mainly for browning. Hot fat seals the breadcrumb coating quickly, while low heat lets the coating soak up grease and turn pale or soggy.
Swap the mace
How well each one fits the dish's main ingredients (potato, fish, pepper, egg, butter):
- Parsleyfits better
- Tarragonfits better
- Nutmegfits better
- Macethe original
Fit is the average pairing score against potato, fish, pepper, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
