Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold fish
- Forms the main body and flavour of the fish cake.
- Mashed potatoes
- Adds moisture and softness, keeping the cakes tender inside.
- Bread crumbs
- Bind the mixture and form a crisp, browned coating when fried.
- Egg
- Binds the mixture together so the cakes hold their shape.
The step that matters
Fry the coated cake in hot oil until golden brown. Oil that is not hot enough lets the coating soak up fat and fall apart, while overheating browns the crumbs before the centre is heated through. Steady heat gives a crisp crust and a cake that stays intact.
Swap the onion
How well each one fits the dish's main ingredients (fish, potato, bread, parsley, pepper, egg, lemon):
- Asparagusfits better
- Spinachfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against fish, potato, bread, parsley, pepper, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
