Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main flavour and the flaked texture of the cakes.
- Mashed potatoes
- Adds starch and bulk that hold the cakes together and keep them moist.
- Beaten egg
- Binds the mixture so the cakes keep their shape while frying.
- Bread crumbs
- Forms a crisp, golden-brown crust when fried.
- Butter
- Adds richness and fat that softens the mixture and adds flavour.
The step that matters
Fry in deep oil until golden brown. The oil must be hot enough to crisp the crumb coating quickly. If it is too cool, the cakes soak up oil and turn greasy before the crust sets, and the centre may stay loose.
Swap the potato
How well each one fits the dish's main ingredients (egg, pepper, butter, bread):
- Capsicumfits better
- Asparagusfits better
- Chivefits about as well
- Potatothe original
Fit is the average pairing score against egg, pepper, butter, bread. Candidates are from the same food group and used in at least 100 recipes.
