Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy bulk that holds the cakes together and gives a soft interior.
- Fish flakes
- Supply the main flavour and protein that give the cakes their substance.
- Butter
- Adds richness and fat, softening the mash and contributing flavour.
- Hot milk
- Moistens the mashed potato so it becomes smooth and easy to shape.
- Flour
- Forms a dry coating that helps the cakes brown and crisp when fried.
The step that matters
Beat the mixture thoroughly and shape it into cakes. Beating works the potato starch and binds the mash into a cohesive mixture, so the cakes hold their shape in the pan rather than crumbling apart during frying.
Swap the potato
How well each one fits the dish's main ingredients (fish, butter, pepper, milk, flour):
- Potatothe original
- Capsicumfits about as well
- Leekfits less well
- Asparagusfits less well
Fit is the average pairing score against fish, butter, pepper, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
