Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leftover eggs
- Bind the mixture and help the cakes hold their shape.
- Mashed or cold chopped potato
- Adds bulk and a soft, moist interior to the cakes.
- Raw egg
- Forms a coating that helps the crumbs stick and browns during frying.
- Cracker crumbs
- Form a crisp, golden outer crust when fried.
The step that matters
Fry until light brown on both sides. Frying over moderate heat browns the egg and crumb coating through the Maillard reaction, creating flavour and a crisp crust. The coating can burn before the cake heats through if the heat is too high, so cook at a steady medium heat and turn once.
Swap the potato
How well each one fits the dish's main ingredients (ham, egg, butter):

Fit is the average pairing score against ham, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
