Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the cutlet, giving a soft, starchy body that holds its shape when mashed.
- Eggs
- Bind the mashed potato so the cutlets hold together during shaping and frying.
- Plain flour
- Absorbs moisture and stiffens the mixture, making it easier to shape.
- Onion
- Adds savoury flavour, sweetness from browning, and aroma to the potato.
- Dried breadcrumbs
- Form a crisp, golden coating that browns in the hot fat.
The step that matters
Frying the coated cutlets in hot fat. If the fat is not hot enough, the breadcrumb coating absorbs oil and turns greasy instead of browning and crisping. Frying on both sides until golden brown also ensures the coating sets and the interior is heated through.

- Onionthe original
Fit is the average pairing score against potato, egg, flour, butter, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
