Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black walnut meats
- Provide the nutty flavour and body of the croquette filling.
- Mashed potatoes
- Bind the filling and add moisture and a soft, tender interior.
- Eggs
- Bind the mixture together and set during frying to hold the shape.
- Bread crumbs
- Absorb moisture in the filling and form a crisp, browned outer crust when fried.
The step that matters
Fry in deep hot fat until golden brown. If the fat is not hot enough, the coating absorbs oil and becomes greasy before it crisps, and the egg may not set properly. Frying at a steady hot temperature seals the crumb crust quickly and keeps the inside moist.
Swap the potato
How well each one fits the dish's main ingredients (walnut, meat, egg, bread):
- Shallotfits better
- Asparagusfits better
- Lettucefits better
- Potatothe original
Fit is the average pairing score against walnut, meat, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
